How do you restore a cleaned coin

How To Clean Coins To Shine Right At Home?

How do you clean the copper coin?

Coin cleaning - labor-intensive irrobuiem process. To clear the exhibition, the number of regulations that are mentioned by the mentioned material is used. Consider cleaning the copper coin in glorious conditions. It helps when you need to clean the copper coins of the otokyse, deacidifiers, degenerate plaques.

Analyze the environmental level if you can help your exhibition. If you cut cleaning coins, thrown illicit alcohol soap isn't necessary. From chemical funds you have to refuse: this is how you can damage the exhibition.

Method 1: soap and water

We take soap (better economical), rub it on the grater. Add 1 liter of water. We leave coins in the solution for 10-15 minutes. Mud splatters, and it can be easily removed with a sponge.

Method 2: vinegar

Put the gloves on, take a soft sponge and apply a little vinegar. Light massage movements wipe the coin off. After that, run the coin under warm water to remove the remnants of the funds. Alternative vinegar can be amazingly alcohol.

Method 3: lemon

Take a fresh lemon, cut it in half. In the flesh of the fruit put the coin and walk for 15 minutes. After the time runs out and carefully clean the brush carefully. In the end, don't forget to dissolve water.

How do you clean the coin of departure?

Putting the collector there are its secrets of purifying coins of the swivel of urine pollution. Each metal has a unique chemical composition, so you need to know what is possible, but it is impossible to restore these values.

To clean the coin from the grate can be used:

  • Vinegar;
  • Citric acid / juice;
  • Lemonade;
  • Coke;
  • Salt;
  • Laundry soap.

All of these means are used by analogy with the above procedures.

How do you clean the silver coin?

The annual day does not exist in the uniform method for cleaning silver coins in wonderful conditions, as everything here is directly dependent on the oxidation. This is due to the stamps they have as observance of integrity methods of cleaning.

Old high-quality copies are cleaned by Schwarz with a solution of ammonia alcohol (90% water). If there is not, then it is manually replaced with a soda solution (300 g of 1 liter of water), which IAOKOLO should soak for 2-3 hours. If you want, you can cook a little solution for better effect. It has to save the cross-exchanger coin that is relevant to old instances.

To extinguish the coin, use the mixture of toothpaste and Ñaxy alcohol soda. This method is good because there are no abrasive particles that can damage silver. This mass should be applied to the flat surface to clean it with a decrease.

The trillion process is suitable for exhibits made from Icelandic silver (Trilon B is a special type of salt). It is necessary to resolve 1 TBP. A spoonful of salt in a glass of hot water, then lower the coins there and wait for the result. However, to deactivate metal, all measures should be carried out in a well-ventilated area. Next, this process needs to be continued by processing a special tool to clean silver a specific sample.

How do you clean the coin of negotiation?

Time is a preeminent cause of black. UAE article from our painting to you how you can clear the exhibits of the pitch. The current top copper layer is oxidized as a result of contact with contact with a compound, so there is a special attenuation companion. It looks like a black torch, eliminate a resident difficult that a skilled restorer is difficult.

However, there are several tricks that can help get rid of a specific problem. Alternatively, the coin can be observed with a cotton disc, moistened with a wobbly alcohol with a fancy rinse with a warmth of soapy solution. The main component of this alcohol is ammonia, which, due to its properties, perfectly reacts with copper oxide compounds.

There is a Iorroy method for cleaning the copper surface - a mixture of oxalic acid, turpentine, ethyl alcohol II water. This mixture can clean the vibrators so that the metal oxide of the metal is so degreased.

How to clean the coin of an abandoned badge

There are cases when you crash how to clean the coin coin. After all, the oxidized coins lose their original, commercial look. The method of cleaning the mark depends on the Oxam type of alloy. It is therefore important to carefully determine what type of corrosion has hit the metal.

There are many types of corrosion, the most common of which is which are:

  • Green spotty oxidized copper surface. It is formed to long-term promote it inside;
  • REDDISTED RAID, most common in the friction found in the ventilated space;
  • Black-colored metal patina attesting to the entire age of metal.

There are several ways to get rid of Subtle Coverage. Safe cleaning of Iszamy with a solution of diluted vinegar. To prepare it, you need to take two spoons of table vinegar in pure water (the videos are distilled). After that, it should be placed with COCOxtte liquid so that it is uncontacted from the smallest surfaces of smallest contact with the capacitance grids that are being placed. This is necessary so that the entire surface of the coin is evenly exposed to acid.

There are many known cases where the coins were placed in stolen quantities in an attached container which resulted in kneurometer injury to the needle skin from stains from more isous areas.

It is also necessary to clean layers in the time that is formed due to the action of the vinegar mixture. It has to be done several times in time to take out the coin. Clean the One toilet toothbrush. It is believed that it remembers that excessive efforts can seriously damage the coin to convert red spots, which are virtually unrestricted without mechanical intervention.

This method helps clean up both heaters, leaving mud stains as easy to see. It takes an unforgettable recovery that there is a full recovery to wait as the structure of the metal undergoes irreversible changes.

How do you clean the bimetal coin?

Renewable numismism knows that any type of alloy requires its nominal approach. The most common problem is such metals, if a coin needs cleaning with anti-corrosion solutions, the one created is in good condition. Inesli according to Ktakim, to apply the usual cleaning with acidic solutions, the chance of harming the second metal, due to such defects, may appear as sweating, to change the chemical composition of the upper layer of the alloy, the change in the primary color.

Therefore the cleaning of bimetal coins in the size of the desired conditions should not be desired by the desired results, it turns out to be an economy level. To carry out such procedures, a soda solution is required (2 hollow hot boiled watercraft). The coin must be placed at 15-20 minutes. It doesn't have to forget the oily comment on her stunning comment. Once pulled out, it is impossible to clean the white toothpaste without coloring. If this is not related, then you can use tooth powder. It is believed that its abrasive particles can leave micro-scratches, so this procedure should be performed extremely gently so as not to obstruct the surface of the MICROCRACK INENST.

If the above procedure is not having enough effect, you can try chemicals to dissolve the lime-based ororosia. To do this, it is necessary to apply a small amount of the gel to the surface of the coin, it is necessary to rub it off with a non-bubbly cloth. If the stains are urgent, you can try the same action, same low usage toothbrush.

After properly performing these procedures, the metal should acquire the color characteristics of it.

How can you clean a zinc coin?

Wincels also have copies of the Qtyne. Cleaning such coins is a very tedious process. This is due to the Stolter, who occasionally reacts with cylindrical acids, but the salt has poor reactivity to XLab acid solutions. Therefore, the most optimal option for cleaning such values ​​is solved by the patina layer of the C1% solution of hydrochloric acid.

Before starting the violation of the metal, it should be remembered that the cover of a liquid can not be left unattended, since it should be checked every 5 seconds. It is necessary to see the moment when the patina has already gone, Ikislota started in a dumping metal.

Cleaning zinc instances in glorious conditions is much more efficient when the container is wide enough. It is necessary to hold the coin of the loop at the same time in order to clean the delicate brush. Salonic acid differs here:

  • It has a different activity from sour cream;
  • Not doing anything harms human skin;
  • It has a good reaction with a whimsical yerezzeque.

After cleaning the coin, rinse with acids using strong water pressure. It is attached to the trunk if you just throw your left hand, an acid is still zinc at night. This can lead to the conspicuous alloy etching which is extremely undesirable for such products.

Complete cleaning of zinc coins in permanent conditions - quite a time-consuming case, do not expect much effect. In love, however, they will acquire a more attractive price for the cost of the cost.

The best ways to clean coins with their own hands

There are many different types, but chemical and mechanical mechanics are the most common. Each of them are good in different cases based on the condition of the coin and the type of pollution.

Mechanical process

Usually used in specially established cases. In this case, the coin is literally cut or restored into the oxide layer.

The simplified procedure looks like this:

  • A surface layer of mud sediment is removed from the coin, after which it is released into a container of distilled water.
  • The layer of surface oxides (including loose parts) is impregnated with a synthetic resin (B72).
  • The swiss, cutters, brushes and needles of different stiffness from the surface are all unnecessarily removed. Resin strengthens, binds, and does not allow loose areas to form a cavity that allows the surface to align.

Work is carried out under an elevation (e.g. a microscope). A successful result directly depends on the unscrupulous relationship and experience, so working with expensive copies is better to charge a professional.

Chemical method

It implies cleaning coins with different chemical compositions depending on the metal from which they are made, as well as the same type and degree of pollution.

In order not to spoil the coin and choose the right composition, you need to learn exactly from the metal what it is made of. There are special chemical compositions, but their cost is quite high.

Features of cleaning products from different materials

When choosing a method and means of cleaning coins, the correct consideration is given to the material from which they are made. The right approach enables the brilliance to be achieved quickly and effectively without damaging it.

gold and silver

Numismatists are usually supplied with specimens made of silver and gold. They need careful care and create special storage conditions. You should carry money from precious metals separately from other currency symbols, otherwise they will be oxidized and will have to be washed much more often.

The right choice of method and cleaning agents will allow you to preserve the glitter of gold coins and their value.

To clean gold and silver, use money, use gentle agents, avoid aggressive substances and excessive mechanical action.

Chemical cleaning

Wash the stains for monetary signs of precious metals with a 10% solution of ammonia. First, tilt the products in distilled water for several days and then in ammonium solution for an hour. After the allotted time, rinse them off and wipe dry.

When working with ammonia, observe precautions: put on rubber gloves and open the aircraft window.

Mechanical cleaning

Mechanical cleaning with a brush with varying degrees of stiffness helps to remove minor impurities. Lower in distilled water with first several days in distilled water. Then buff it with a toothbrush to carefully clean the surface. To remove heavy contamination, use a weak SOAP solution as well.

copper

Clean copper coins can be made by various means. The choice of method depends on the type of pollution. To remove the red soil, soak the trifle in 5% ammonia solution for 2 minutes. A solution of citric acid helps remove green pollution and yellow acetic acid.

To protect the medium from the negative influence of the environment, evenly cover their patina - a special protective layer

After cleaning the media, follow the final deposit phase:

  1. Rinse the products with distilled water.
  2. Well dried with a napkin or a soft towel.
  3. To create a protective layer 50 g of copper sulfate, dissolve in 1 L of distilled water and add 5 g of potassium permanganate. Heat the mixture to +90.
  4. Suppose the products are in the solution and stand a few minutes. During processing, turn them over periodically so that the patina is evenly covered with the surface.

Nickel and bronze

Nickel and bronze products can be cleaned independently at home with branded or special agents.

Salt and vinegar

Step-by-step cleaning instructions:

  1. Prepare a solution based on cutlery and salt.
  2. Soak nickel money in liquid.
  3. After soaking, treat the surface with the eraser, then buff the soft napkin.

After cleaning, the little thing inevitably rolls off with running water and wipes the soft dry cloth or a paper napkin

"TRILON-B"

Prepare the glass container and TDONL-B tool for cleaning. Put the powder in the container and fill with boiled water. Finish the money on the solution, leave until cleaning cleans the pollution completely, then dry and polish.

Bimetal

Bimetal coins are an alloy of several metals. When choosing a method and cleaning products, it is important to consider the functions of each of them.

Safe and effective means of cleaning ten meter bimetal coins:

  1. Toothpaste. Apply a small amount of agent to the brush and handle products under the running jet. Keep in mind that the little thing can get a little dark after cleaning.
  2. "Coke". Soak bimetallic rubles in a carbonated drink for the night, and rinse and dry well in the morning. To get the maximum effect, repeat the procedure within 7 days.
  3. Formic acid and alcohol. Prepare a solution based on part data and surface the items for 5 minutes. This processing brings back gloss and beauty coins.

To clean money from the bimetal, choose gentle agents to avoid damage to valuable copies (on the photo bimetal coins with par 10 rubles)

Do we spend money on purchases or side dishes?

Specialized solutions have been created, dedicated to the cleaning processes designed taking into account the specifics of each specific metal: copper, silver, etc. With each of the funds presented on the shelves of housekeeping, you can remove various pollution and uneven patina from the surface of coins, oxides.

However, in order to restore copper and other metals to their pristine appearance and purity, not everyone can afford to purchase these rather expensive solutions.

Hence, most ordinary consumers choose to poke the copper surface of coins by cheaper and less expensive means.

Alternative cleaning methods acceptable at home can clearly clean virtually any contaminated copper coin.

The list of required funds available in most households is as follows:

  • "Coke";
  • Citric acid;
  • Soap;
  • Electrolysis.

With the help of each of them, many ordinary consumers have been able to clean the copper surfaces of coins and other products made from this and other metals.

The algorithm for cleaning copper and silver coins is characterized by the same simplicity and availability, as well as similar copper products. Numerous Internet resources contain all the information you need.

The following review is devoted to the problem of cleaning copper coins in a number of ways.

Coin cleaning tool.

There is no safe and strict cleaning procedure for ancient coins as coins can vary in cooperation, age and condition. To develop cleaning techniques, you need to experiment and practice. So soon you will find the cleaning of old coins that is the most suitable.

Brushes - Very useful tools for cleaning clinker coins at home. These brushes can be bought in the store. It is recommended to use brushes with copper and steel bristles made of plastic, copper and steel. Copper bristle is more versatile as it is tough with plastic bristles and soft steel bristles. Copper bristle brushes do a great job of cleaning vintage coins. If there isn't one in particular, you can use a traditional toothbrush.

When cleaning vintage coins, never use a metal tool to directly impact the surface of a coin made from a delicate metal. This can lead to scratches and even deeper damage. Use steel bristles only to remove the external layers of dirt with coins. Use plastic tools whenever possible.

Aside from brushes, there are other useful tools that can be used to clean the vintage coins. Toothpicks, pointed wooden sticks, straight pins, toothbrushes and erasers - all of this will be very much, by the way. Maybe all of that already at home. However, you can buy such a simple "device" in any commercial store with a minimal cost.

Cleaning coins at home using distilled water and olive oil

The first step in cleaning an old coin is to submerge it in the water. It will weaken scaling and debris, which will ease the process of removing them. Use distilled water as tap water can contain minerals that are harmful to coins. Move the coin around for a day or two, then pull it out of the water and lose it easily. Perhaps this procedure has to be repeated for several days or weeks depending on the contamination of the coin. After soaking the coin in the water, it is necessary to extinguish it dry.

If distilled water doesn't produce the results you want, try the soucke a coin in olive oil. Place the coin in a closed plastic or glass jar for a week. Check the dirt status and repeat the process. After the process is complete, all of the oil must be removed from its surface. Use a non-aggressive detergent for this.

For quick results, you can use chemical cleaners designed specifically for metal surfaces. Use these cleaners with caution as all coins are different. The chemical reaction can be unpredictable, so the first experiment with less valuable coins. Always read the instructions carefully before using the chemical to ensure that it is compatible with the coin composition.

Silver coins cleaning rules

Silver coins can be washed with citric acid, table utensils, ammonia alcohol, Trilon-B, and solution, which is made on the basis of food soda. It should not be used in dry form. This is with the appearance of small scratches. A good effect can be a homogeneous mixture, which includes ammonia alcohol, toothpaste and soda. Before using it, you need to be sure of the absence of abrasive particles. Observing recommendations for cleaning the old silver coins can greatly improve their appearance.

Safe cleaning of old and collectable exhibits at home

Among the means that can help in the appearance of pollution on the surface of valuable copies without harming the sweetened water and onion juice. Special compositions are mostly made on the basis of oil or petroleum jelly. After finding in a liquid medium, the coins should be woven with a soft cloth. Use gels designed for washing dishes, and plumbers are prohibited.

The regularity of cleaning determines the numismat itself. If it is not to sell on coins, there is no great need for careful and expedited processing. Exhibits that are especially valuable are recommended to clean special compositions. In the absence of confidence in their own knowledge and experience, professionals should be trusted. Corrupted coins in most cases are not subject to recovery.

Old products, unlike modern ones, are not protected from external influences. When cleaning, it is necessary to take into account that the strength of the antique products is greatly reduced. Therefore, when choosing a means of processing them, preference should be given to gentle and safe preparations. How to erase old coins at home, which are indicated in the instructions.

Cleaning citric acid coins with liquid soap

The procedure is gentle, suitable for removing small impurities. But if the coin is rare, then without experience it is no better not to experiment with acids. To begin with, check the method for less valuable finds.

To make the solution, we mix 100 ml of water, a third of a teaspoon of food citric acid and two teaspoons of liquid soap, better than children. I lower the coin into the solution and need to continue immediately. "Greens" are removed with a cotton stick, a small relief can be cleaned precisely with a toothpick. Do not use metal! Lemonock interacts with oxides quite intensely, so it's not worth keeping in solution. Wash with water after cleaning.

Coca-Cola cleaning coins

Favorite drink from childhood can not only clean the pipes, but also coins. Particularly well on the aggressive Coca-Ring medium, oxides react to copper-Nikiliyevy alloys. The recipe is simple: pour a shopping cola into a cup and lower coins there for at least two hours. It is only necessary to take into account that with this alloy all kinds of impurities can play a cruel joke with you: instead of the wonderful effect of a clean coin, you can get a bald one - the relief will be erased, with what is palpable.

Cleaning the coins of the USSR in Coca-Cole appears after 4 hours: it is noticeable that red is recognizable, and the dirt also did not stand up to the chemical composition of a tasty but dangerous drink.

The best way to clean the silver coins is "soup with a cola", that's what I call it :) The method is great for cleaning silver coins when the patina looks bad and the relief doesn't give. For deep cleaning, the coin must be welded on a slow fire in a colleague. How much to hold - depends on the coins "Kill", you will notice the difference visually. Cook in boiling mode for 3-5 minutes. Only wash the field of complete cooling of the coin!

Cleaning coins from rust does not require that the device simply be wrapped in a cotton rag moistened in the drink and leave the clock by 6. If you are simply pouring a cola coin, it should last at least 12 hours.

By the way, if you are lucky enough to solve the problem of cleaning gold coins, the cola is very much. It will not injure the metal, erase the relief, clean it carefully, and there is no need to scrape the coin with a mechanical tool.

Coca-Cola cleaning coins

These are the two of my favorite ways to fully clean coins or prepare for further mechanical cleaning. And now about the third method that I don't use, but I'll say a few words about it because of its unprecedented popularity.

Vinegar and toothpaste.

Universal means getting rid of the oxidation and rust. To do this, mix the table vinegar and the paste in the 1: 1 ratio. The resulting mixture is released along the surface of the coin with circular movements, after which it is rinsed with cold water.

Clean the products with a brass brush and tumble the remaining solution off the surface with warm water.

Boil "oil"

The procedure is quite effective and allows you to wash off the patina. This is done using olive or petroleum jelly oil, which is poured into a metal pan or deep fryer and heated. Coins are lowered into hot liquid and boiled for ten minutes, after which it is washed with soap and a soft brush.

Warming Vaseline or vegetable oil on a water bath. Soak the trifle in the hot liquid for 10 minutes.

Notice! In some cases, additional boiling in pure water is required to remove any oil residue.

How can you clean the old coin?

In order for the collective object not to lose its value, it cannot be purified of brilliance, since it negatively affects the security of relief. Rude mechanical or chemical cleaning is also invalid. Since old coins can be very fragile, in most cases they are either not cleaned at all or cleaned with special gentle agents. It is also permissible to use electrolysis.

After studying all possible ways to clean coins and choosing optimally acceptable ones, you need to observe the accuracy of each step.

Purifying the coin is a subtle and responsible process that you must carefully prepare for. Subject to all the rules, you can get a neat and restored collectible.

How to effectively clean the coin from rust

To remove rust, Trilon B, as well as various acids - sulfur, salt lorsics, ants. All are very active and so the response must be constantly monitored. After cleaning is complete, the acid must be neutralized, which can be done with a soda or soap solution.

Electrolysis process

With this concept proper attention has been paid to the school desk familiar lesson of physics. Its advantage if the processing of coins is ensured by two important rules:

  • Security compliance;
  • Testing the method on inexpensive copies to avoid damage to more valuable products.

It is worth paying special attention to the second point of jobs: the fact is that other times, due to the small mistakes, serious, irreparable damage to a coin or other valuable product is made due to the small mistakes.

Old coins are restored for purity and luster with a small power supply unit (6-12 volts). As such, universal charging can be used. Another alternative: an old charger from a mobile phone.

For the power supply or its alternative option are attached:

  • Two brackets like "crocodile";
  • a small metal object (not recommended made of copper or brass);
  • Deep utensils made of glass or ceramic.

A saline solution is also used, observing the following proportions: 1 tablespoon of salt by 1 liter of water.

The process is marked for simplicity, you just need to carefully follow each step. A clamp - with a minus sign - attached to the copy, while the opposite - with a "plus" sign - up to a metal object.

Then the coin and metal product are lowered into a pre-stretched container where the saline solution is located while the power supply is switched into the outlet.

The result lends itself to knowing pretty quickly: the process of dissolving oxides and dirt leads to a quick dissolution of the solution. The "bathing time" is short, after which the instance is washed with hot water and dried.

A little attention and the clarity of all steps will allow you to achieve the desired results.

Mix together soda and soap

If you want to achieve the desired purity in the shortest possible time, the procedure can be strengthened with soap with the use of soda. However, add soda already in a dissolved form.

After cleaning, the coins should be rinsed as possible, lubricating it with alcohol and petroleum jelly ointment. The final step provides maximum protection from the appearance of new pollution and oxidation.

Extreme cases

If the coin is brought into an extreme condition: it is unusually dirty, you can resort to the ridicule of SOD. You need to handle the means very carefully, it must be grown in cold water.

Since this agent is essentially a strong alkali, it is recommended that you avoid contact with it. It is necessary to lower the product onto this solution with tweezers. Duration of stay in solution: no more than ten minutes, after which the coins are received and washed.

However, not all coins can transfer this method. If there is a stain of a green or blue color on its surface, the cleaning process must be stopped. With a negative reaction, it is not necessary to use this method on products that have already been tested.

After studying all possible ways to clean coins and choosing optimally acceptable ones, you need to observe the accuracy of each step.

It is also necessary to take care of your own safety - especially when using some methods.

Clean, brilliant and sparkling coins are satisfied with their appearance by both connoisseurs and connoisseurs of these products and ordinary users, for one reason or another, interested in cleaning bound copper coins and other metals.

What is not recommended to clean the products so as not to damage them

Different alloys react differently to a certain processing method. However, there are a few ways that can equally damage the surface.

  • The heat treatment can melt some metals and cool down after cooling.
  • Metal pile and sandpaper change relief hard brushes.
  • The effects of sulfur, nitrogen and hydrochloric acid concentrates melt the hunted relief.

Storage after cleaning

After all the procedures, the product must be wiped dry with a soft cloth and towel. Copies that have value should be stored in a dry place away from sunlight, and as you can pick them up. It costs each instance separately in special boxes, albums, and other things.

If the patina was damaged during cleaning, it can be artificially imposed. It will give a noble look and protect from subsequent corrosion. Place products in a solution of 10% of the hyposulfite for a few minutes and they will cover the patina again.

Different alloys need individual cleaning, so before starting metal it should be determined what metal coins are made of and guided by the above recommendations. Security assurance is required when performing these procedures.

Loading...

All coins have a property that has become soiled over time, covered in rust and bloom, which not only makes them unattractive but also illegible. However, it is necessary to enter the cleaning of coins at home so as not to damage the alloy.

The question of cleaning the coins shows a lot of numismatics.

How to clean coins

Brilliant polished coins look spectacular, and if grease or dirt appeared on them, then it is definitely cleaned. However, the surface of the coin can be covered with patina-uniform oxidation, which indicates a long history and protects against external influences. This gives the money precious species, and therefore the masters often create an artificial patina, a short period of time in a coin. However, oxidation can cover the surface and imprecise divorces and separate stains, and then cleaning is already warranted. Right, there may be other defects such as small cracks or scratches under the layer of stain.

It happens, an example comes through the collection from the treatment or a coin was simply kept in inappropriate conditions and was often taken by hand without gloves.

For some types of coins, cleaning is categorically contraindicated, as the vintage samples are categorized, and unless this is not in the best condition, they will receive additional damage, reducing their value and cost. Such cases are recommended to wipe only from dust and traces of fingers, and then put in a protective container.

If the surface pollution can be washed with soapy water, then everything is more complicated with the oxidation.

Important! When cleaning the coins, it is not necessary not only to repel the alloy, but also to avoid the use of abrasive tools as they can spoil the thing.

copper

Copper more than other metals are subject to corrosion, which causes green (due to moisture) on its surface, red (no ventilation) or black (patina) to flare up. Cleaning copper coins requires extreme caution, as corrosion processes often provoke the appearance of recesses and cracks that destroy the product from the inside. Therefore, before cleaning, it is important to carefully examine the copy of the instance. The effectiveness of cleaning methods is non-etinak and depends on the level of the environment and the accuracy of the work.

Cleaning should be done taking into account the specifics of each specific metal.

As a rule, use such techniques:

  • 5% AMMONIA solution or a diverse solution against a red plaque;
  • a solution of lemon or oxalic acid for green plaque;
  • Acetic acid solution against a yellow floor.

In all cases, the coin is lowered into the solution for two minutes, after which it is washed with running water and thoroughly washed with cloths.

Important! The proposed cleaning solutions are quite aggressive, have a pungent odor and are easily flammable, so it is possible to work with them only in tight gloves and with good ventilation of the room.

Most of the commonplace consumers choose to lay the copper surface of coins using more affordable and less expensive means.

After removing the badge, the cleaning of the dirt is entered. It does this by placing copies in boiling distilled water with petroleum jelly oil. After washing with alcohol is required.

silver

Pick the concern of concern of the silver coin based on the sample and the degree of oxidation. The composition of the sample can be different and therefore the approach should be different.

Cleaning silver coins - the process of knife convenience and time consuming.

Notice! Almost all modern metal cleaners are acid based, and therefore their use to clean the coin is to remove the metal surface. Therefore, the copy loses its collective value and contains a smaller amount of silver.

The following methods are used to clean silver coins:

  1. Soda and citric acid. First, coins are placed in water with citric acid for twenty minutes, and then cleaned with soda with a small amount of water. After manipulations are washed with clean water.
  2. Sulfuric acid from divorces and green spots. In acid, diluted with cold water, the coins are placed at a specific time. After the help of dense rubber gloves, removed, clean with a soft brush, rinsed with clean water and swell dry.
  3. Ammonia. Silver copies are placed in alcohol for twenty minutes. At this point, they cannot be removed to avoid contact with oxygen, but it can be turned over. After a while in the container, it is necessary to slowly pour water until its amount exceeds the amount of alcohol, after which the coins are removed, cleaned with a soft cloth, washed and dried. The procedure cannot be repeated more than three times.

The rules for cleaning silver coins at home require a competent choice of means and compliance with the sequence of actions.

For basic silver coins, you can use TRILON B - special composition, which is a kind of salt. It is mixed with water in the amount of one tablespoon. Immersed in the copy is purified of itself.

Golden

Gold belongs to the group of inert metals, so it reacts poorly with other elements and is therefore resistant to oxidation and is weakly subjected to corrosive processes. At the same time, this metal is very soft, and therefore it is necessary to handle it extremely gently, especially when cleaning.

It is enough to remember one simple rule: gold coins, as a rule, do not need long and aggressive cleaning.

Older gold coins made from high-quality pure gold samples are not at all about oxidation, but the patina happened on later copies. This is explained by the presence of a variety of impurities in the alloy. In addition to possible oxidation, gold can be covered in dirt, dust, and even paint, and so it is often necessary to clean it. The following methods are used for this:

  • Washing powder or economical soap. The detergent is mixed with water in the metal tank in which the coin is placed. You can either boil the solution for 10-15 minutes, or let it sit for several hours. After completing the procedure, it is necessary to carefully remove the coin using rubber gloves.

Sometimes a pretty common soap solution and a decent cleanup.

Notice! The use of metal tweezers or staples is extremely undesirable as it can be damaged by an instance, leaving the scars on it.

  • Soda, salt, or sugar. Soda is more common, but the effect of all three tools is about the same. The glass of boiling water needs a spoonful of dry matter. A coin is placed in this solution for eight hours, which is after the need to rinse with clean water.

Cleaning soda refers to alkaline methods to get rid of dirt.

  • Summer charcoal and hydrogen peroxide. A glass of water needs a spoonful of alcohol and 30 ml of peroxide. A coin is placed in the solution. that can be extracted after 15 minutes. After cleaning, it must be rinsed with microfiber and dried.

It is necessary to mix the ammonia solution and hydrogen peroxide.

Bimetallic.

The complexity in cleaning bimetal coins is that they are made up of several metals, and each one has its own characteristics. Usually silver and steel are used for the center, and for the edges - copper and gold. Such methods are the same:

  • Detergent (for example comet or fairy). Built-in water in the ratio of one tablespoon per liter and applied with a soft sponge.
  • Toothpaste or paste in gay. It is applied to a soft toothbrush, cleaning coins under warm water.

It is sold in commercial stores, it is inexpensive.

Notice! This method can result in minor fading of coins.

  • A solution of alcohol and formic acid. It not only helps to delete the instance, but also to restore it. Coins are lowered into the solution for no more than five minutes, after which they are withdrawn, washed with warm water and wiped with a clean cloth.
  • Coke. This is a long time. Coins must be placed in a drink for at least one night, and if the result is unsatisfactory, then for a long time. After extraction, they need to be rinsed with cold water and thoroughly wiped.

Coca-Cola contains a large amount of orthophosphoric acid, which effectively removes small traces of contamination and corrosion.

Zincovaya.

Clear zinc coins are quite difficult as this metal begins to darken after contact with many substances that come in lean. Only the following methods are used:

  1. 1% hydrochloric acid solution. It is poured into a wide container in which the coin is placed. It is necessary to closely monitor the reaction and remove the instance after removing the contamination, but before the start of the destruction of the metal itself. Otherwise, the latter can be resolved in a few minutes. After grasping a coin, it is necessary to carefully rinse with water to prevent the reaction from continuing.
  2. Lighthouse. This is a liquid specially formulated to clean zinc coins. It does not contain any aggressive ingredients and therefore does not damage the metal surface.

Liquid lighthouse can be bought in specialized numismatic stores.

bronze

Compared to other materials, bronze is pretty simple. The following methods are used:

  1. Table vinegar and salt. Components are mixed, and the coin is placed in the solution. After a short time, it is extracted with the help of tweezers and rubbed with the eraser. If necessary, the procedure can be repeated.
  2. TRILON B. A small amount of this powder falls into a transparent container with boiled water. A coin is placed in the solution, and it remains there before visual cleaning, after which it is neatly removed, washed with cold water and thoroughly cloths washed.

TriLon removes all growth and oxides to "0".

Cleaning coins with special means

Done means you are cleaning coins effectively and safely. However, it is necessary to choose them so that the collective object does not lose its value.

The algorithm for cleaning copper and silver coins is characterized by the same simplicity and availability, as well as similar copper products.

The following compositions are the most popular:

  1. Insert paste "Asidol-M". It has an unlimited shelf life, consists of surfactants and a small abrasive. Suitable for cleaning all types of coins (except particularly valuable ones), as well as other metal products.
  2. Insert "USSR". Contains Nanodispess abrasives, sodium bicarbonate and sodium potassium tartrate. It has an ignorant smell. Suitable for products made of brass, bronze and copper.
  3. Means "modern Russia". It consists of nanodisperse abrasives and organic acids. Suitable for cleaning bimetal and galvanic coins.
  4. Preparations for cleaning copper copper coins. Contains anti-corrosion components. The active ingredient is an oxidizing agent of higher transition metal oxides, which is why work with the agents should be carried out in special protective gloves.
  5. "Trillon B" powder. The budget option is effective in cleaning copany coins that are minted by a metal. Copies are placed on the margin to improve performance. The tool causes irritation of the mucous membranes, so the safety glasses are necessary for the work.
  6. Means for passivation coins from glossy coins. The paste contains petroleum oil and substances that prevent corrosion. Used to protect coins from corrosion and sweating.
  7. Means "Nano Pathina". Made on acid and copper sulfate. Suitable for cleaning metals.
  8. Recover the mirror surface from glossy coins. This is a strong solution made on the basis of acid and complexing agents. Used to remove fingerprints and patina from the surface of silver coins.

Cleans the patina and removes fingerprints.

Use of budget funds.

citric acid

This cleaning option is carried out under constant control. When doing this, it is better to remove coins several times and check their condition to avoid damage.

Citric acid coin cleaning is carried out when there are various impurities on the surface of the product that are not removed in the SOAP solution.

In order for the solution to help get rid of oxides, but not harm the metal, its concentration should not be more than 10%, that is, 90 ml of water accounts for 10 g of citric acid. Coins are immersed in the resulting solution, periodically inverting and checking, and after washing, under clean water.

Soap mortar

This is the gentlest option, often used as the first phase of cleansing. However, it can be delayed for several months. The method is based on the fact that the SOAP solution is a weakly alkaline medium that contributes to the gradual softening of oxides and other impurities. Children's soap has the smallest alkaline environment, and the largest is economical. The first is preferred when processing copper coins.

Cleaning coins in the soap is the most common way as it is one of the most delicate and affordable methods.

The cleaning process is:

  1. Grid to guess or finely chop the soap, then pour hot water. Must be viscous, gelatinous mixture.
  2. Place coins in the solution. They must be completely covered with the composition and not touch the walls of the container and with each other.
  3. Stirring and turning coins regularly.
  4. After the soaking is over, the copies are cleaned with a soft brush and washed with warm water.

Soap leaves a distinctive white flare that is easily removed by soda.

Vinegar and toothpaste.

Universal means getting rid of the oxidation and rust. To do this, mix the table vinegar and the paste in the 1: 1 ratio. The resulting mixture is released along the surface of the coin with circular movements, after which it is rinsed with cold water.

Clean the products with a brass brush and tumble the remaining solution off the surface with warm water.

"Coke"

The drink contains a small amount of orthophosphoric acid that can help remove minor pollution. To do this, it is necessary to place the coins in the gas composition, which will be poured into transparent non-metallic dishes for several days. The liquid can be heated a little to speed up the reaction.

Many people know that this drink has a purified effect and is useful in the hunt for a shine.

baking powder

The department is carried out in the coin cleaning in the soda solution, consisting of half a liter of water and 3-5 spans of dry matter. Copies are immersed in liquid and digested over half an hour.

In the case of copper coins, soda is considered a very gentle cleaning process.

Boil "oil"

The procedure is quite effective and allows you to wash off the patina. This is done using olive or petroleum jelly oil, which is poured into a metal pan or deep fryer and heated. Coins are lowered into hot liquid and boiled for ten minutes, after which it is washed with soap and a soft brush.

Warming Vaseline or vegetable oil on a water bath. Soak the trifle in the hot liquid for 10 minutes.

Notice! In some cases, additional boiling in pure water is required to remove any oil residue.

Electrolysis as a cleaning method

Quite an effective but unsafe method. After processing, any existing defects on the surface can become more visible on the surface. The procedure for such:

  1. Remove the plugs on the 12 volt power supply and divide the wires in two by checking the ends. Copper wire twist and solder on metallic brackets.
  2. Prepare an electrolyte from the water halves and a tablespoon of the table salt. Pour liquid into a plastic bottle.
  3. Dip the clips in the water when the power is on. The hissing bracket is positive and it is necessary to put a coin on it. Metal object is attached to the negative.
  4. The cleaning takes several to 40-60 minutes. After its completion, the electricity is turned off, the coin is removed and washed with a warm soapy solution.

Purifying coins by electrolysis is a risky path, especially for a beginner, so start with copies that don't present much value.

Important! To avoid a short circuit, it is impossible to make contact with the cathode and anode contacts.

How to effectively clean the coin from rust

To remove rust, Trilon B, as well as various acids - sulfur, salt lorsics, ants. All are very active and so the response must be constantly monitored.After cleaning is complete, the acid must be neutralized, which can be done with a soda or soap solution.

How can you clean the old coin?

In order for the collective object not to lose its value, it cannot be purified of brilliance, since it negatively affects the security of relief. Rude mechanical or chemical cleaning is also invalid. Since old coins can be very fragile, in most cases they are either not cleaned at all or cleaned with special gentle agents. It is also permissible to use electrolysis.

After studying all possible ways to clean coins and choosing optimally acceptable ones, you need to observe the accuracy of each step.

Purifying the coin is a subtle and responsible process that you must carefully prepare for. Subject to all the rules, you can get a neat and restored collectible. Source: severdv.ru.

Not only collectors, but ordinary people sometimes face the need to clean the coins from rust in order to give them a presentable look. Cleaning coins at home are distinguished by their simplicity and accessibility, you just need to follow the basic rules. To enjoy old products made of expensive metals, covered with a dense layer of oxide, it is better to turn to professionals in the absence of due experience. You can do this and independently, but first you need to understand the existing effects on different materials and choose the optimal means.

How do you clean coins with chemical reagents? As a solvent from oxide and other undesirable plates, the ammonia alcohol, soda, soap, washing powder can be made. A good result will be an impact of vinegar, lemon, or hydrochloric acid. True, the last resort should be used very carefully.

To remove the contamination from most coins, you can use Soap mortar . For example, if you need to clean 10 rubles from a light case, then you just need to soak in a solution of soap and warm water for 2-3 hours. This technique is also suitable for bimetal instances from 10 rubles, which are demanding demanding. In the case of a heavy RAID, all you need to do is increase the exposure time before the day. To ensure brilliance, clean coins are washed in dishwashers.

Alkaline cleaning. Soda simply needs to be diluted with a small amount of water before forming the cashitz that is applied to the coin. After a few minutes, the tool will begin to act and you can proceed with the surface finishing with a soft brush.

The effects of citric acid and vinegar. The solid metals option is widely used for coins and bronze products, steel. It can get rid of the rack rust and a dense hydrochloride. A bunch of citric acid and soda is made by lowering the coin. Very aggressive variants of acetic and citric acid treatment options are not recommended for products made from precious metals. Gold, silver, and even copper can change color under their influence.

Processing by ammoniacal alcohol. This reagent is often used to clean silver coins, copper and its alloys. You just have to lower the product in a clean product and through time to check the quality of the effects. It is important to take into account the specifics of working with the ammonia alcohol and ensure that the room is well ventilated.

The most dangerous but very effective approach is electrolysis . A coin under a layer of rust or dirt is placed in a weakly salted solution in which the electrical current is supplied. Even the toughest dirt can be removed in 30 minutes.

Mechanical restoration. The pollution is cleared with special tools. Brushes, fabric shortenings, scalpels, needles, and even drills can be used. Such an approach will allow you to get rid of any contamination, but there is a risk of damaging the surface of the coins.

Digestion. The products are immersed in boiling olive or petroleum jelly for 10 minutes, then washed with soap and water and processed with a brush. At the end of the approach, coins boil in distilled water.

The cleaning process must be constantly monitored so as not to spoil the product. If the traces of the oxide change dramatically, turning blue or green, it is better to wash the subject and contact the specialists.

Sincerely, author of the channel "Practical advice to housewives - TVJAM.RU portal" Maria Andreeva.

The question of cleaning the coins shows a lot of numismatics. It happens, an example comes through the collection from the treatment or a coin was simply kept in inappropriate conditions and was often taken by hand without gloves. If the surface pollution can be washed with soapy water, then everything is more complicated with the oxidation.

My house was dirty, oxidized bimetal coins and I wanted to clean them. There are many ways to clean coins on the internet. I read various materials, opinions on the forums, watched the video, and finally chose a method of cleaning with vinegar.

One of the dirty coins from the vocation that I cleaned up, for example.

In a jar or plastic container, salt is poured, vinegar diluted with water is poured. Choose the proportion yourself. The larger the vinegar, the faster the coin is cleaned (in the pure vinegar it was cleaned in 5-10 minutes, and in aptic beings, literally in front of the eyes), the more water, the more distant effect on the coin.

The salt is not required to turn the coins. It creates a porous pillow and vinegar exposure on either side that goes to a coin. The rate of its dissolution in water depends on the company that produces the salt. In the photo below, I hadn't resolved to the end for years, and then I tried another one, it resolved very quickly.

Plastic container from the ice cream, which is closed by a lid. Put a dozen and a half coins at a time here.

I usually leave coins for the night or put the morning in the acetic acid solution by checking the evening. The concentration of vinegar, which I wrote as already, as had already written, is focused on the smell, is usually enough to make a coin at this point. In difficult cases, when there is heavy oxidation, I leave the coin another one or two times.

After looking in vinegar on the yellow brass rim, the coin is pink raids and on the spot formed by black oxidation points - saturated red spots.

The coin was happy, but the brass appeared brown stains. This is not dirty copper.

Rinse the coin with water, wipe it dry with a paper napkin or soft cloth. To remove the outstretched copper, I smear the blush places with iodine and wait for it to dry. I tried to make an iodine solution, to interfere with water in a glass of water and toss a coin there. But in the end it turned out that it doesn't simplify, just complicates the cleaning process. When the coin reaps it becomes completely boring.

Literally in a few minutes later in the iodine solution, the copper coin was so heavy for me that I then had to bring it to the acetate solution in the night to restore the brilliance. Therefore, it is better to smear with a wand or tassel with a chopstick. You can use wands with cotton on the end but I didn't find them at the time of cleaning.

Anointed iodine problem areas.

After that, the coin with water and real toothpaste would again dare to squeak on his finger. There are different opinions on the internet. Someone cleans the coins from soda, someone perber, someone with a tooth powder, someone even polarizing coin. Some even prefer an extremely brass brush. At the same time, everyone criticizes the procedure of another who starts the obtained microkenarpine.

Try to work in gloves because cleaning the coins "eats hands" at all stages, from removing vinegar and stopping wiping off toothpaste.

I chose toothpaste because unlike soda, without large particles. Some are offered to rub the coins with a short bristle toothbrush, but a finger is kind of delical and less risky to crush the coin. Even so, it is necessary to be careful with the use of Melchior in the middle. If the condition is close to stamped glitter, then if it is rubbed too actively, a stain will appear in that place. I had coins as I just am not a coin and I have no problems (e.g. Bimetallic Gagarin), and something rubbed is not so much, and the brilliant coating in this place went out and turned out to be a stain (e.g. on) 55 Years old victory Politruk, Ministry of Foreign Affairs). In principle, in the forums, people who scold the metal of modern anniversary coins of Russia are right, the same Soviet pennies are much better concerned about cleaning.

Coin after pre-cleaning. It's already difficult to clean in gloves in the gloves, so I remove it and read the attached napkin with the toothpaste dripping on it.

The result of the pre-cleaning in the photo is higher. The coin was clearly erased, the brass field acquired a smooth yellow color. The main cleaning is now over and the fine work begins. When red spots are cheap again - again with iodine and then clean the paste. If there are black spots that don't rub off, put it back in the vinegar. If there are no stains, clean the paste from dirt in the corners of the letters and numbers. After that, thoroughly wipe my coin and dry. It takes care of the cleaning, usually light yellow and dim.

After cleaning, I put the coin on the window sill in a glass vessel, and there it fries in my sun and acquires a noble cabinet atina. The glass rotates periodically. Sometimes during such a room, red spots can get some coins off. It is enough to confirm iodine, and then rub the paste, after which we put the coin back in the glass.

To secure the coins from these stains, after the final cleaning, you need to dilute in a glass of soda and throw there for 10 minutes, then rinse with water and wipe. Soda neutralizes chemical processes after interaction so that no stains should come out of the coin.

You can put a coin in the album after cleaning the shelf or immediately, but according to my observations on the windowsill, they will be covered by a patina faster - enough two weeks.

Coins on the window in a glass jar. There is a process of patina formation.

Soviet copper copecks and Melchior are also perfectly cleaned. But I do not notify clean copper with a bimetal in a bank with vinegar. It is better to put coins of only one type in a container. As soon as I got up for the night of the coins, as usual, tossed a couple of highly oxidized copper coins for bimetal dozen. Before that was normal, but this time something went wrong, maybe the ten themselves were problematic. In the morning I found out that the solution had acquired a pink color, all the coins were with strong red cracks and three were completely black. Not just the brass ring, but also a Melchioron center. If the pink coins became toothpaste after the fourth, multiple uses of iodine and wipes, I could only worsen the condition of the black coins of iodine by only worsening them by making them even darker. I froze them in a new vinegar solution, regularly looking at the process and only in a few days the black shoes. Two, I was still able to lead in a normal form (Gagarin and Tatarstan) and one (Kurgan region) and kept blushing. As soon as I smothered it with iodine, I started looking for black. I had to buy a new one, the benefits were inexpensive. Maybe the metal is such a low quality.

Also, don't keep coins in vinegar for too long. In some videos they say nothing will happen to them. But I once naturalized in the Acetic solution of 2 kopecks from 1989 with a stamped glitter to get rid of a small stain and forget about a coin for a few days. When it took out it was all dim, in the red spots that were very difficult to clean with iodine. Therefore, the coin in the vinegar is not worth it. Although some foreign coins from Melchior, which were heavily blackened, I was in a weak vinegar solution to clean them.

You can soak more coins in ammonia alcohol (ammonia) for cleaning, it doesn't blush coins as much, but it's weaker brushing and even with water, personally diluted to me, is a lot more unpleasant odor than vinegar.

Coin after cleaning and two weeks in a glass by the window. The brass ring was covered with a patina. The fact that this is the same coin that was when it was cleaned makes it easy to identify the long scratch under the letters L and E across the face of the coin.

Here is my cleaning experience, tested for a hundred coins. I cleaned Russian bimetal, 10 rubles of the mad (City of Military Glory), modern and Soviet head corners, something foreign. Before cleaning any specific coin, the first thing you should do is figure out what it does, and then read about people's experience on the internet with this guy. Copper covered with a thin layer of nickel alloy, for example, better vinegar, not to clean or quick to remove. Otherwise, copper will start to appeal over nickel, and when you start tampering with iodine and paste it will just start getting to the plating.

The main thing before cleaning is worth thinking about possible and whether it is necessary to clean this coin at all. Patina is formed on old coins, which gives them a special charm. In addition, the pollution can hide defects and only worsen the appearance of the coin if the rods open on it. In a word, the process of cleaning coins requires approaching the head.

Some will say why the coins are clean when the UNC is easier to buy. First, the price factor. Not every coin can be bought in excellent condition for a modest amount of money, for example, there is such a bimetal that costs hundreds of rubles in stores, I am not talking about cheap. And then even coins can be in perfect condition in capsules if they were picked up by hand without gloves. I read on the forum when a plow three times my collection of DHS was changed due to the fact that it was tried. What he simply did not invent for storage, the expensive German capsules also bought. To clean the coins, you do not need to sprinkle ashes on the head and tear your hair on it. Dramed - cleaned and no problems. Although of course this already gives deep oxidation and the black dots on the maddened, it is difficult to remove and clean the expensive copies, e.g. B. cheap, it pays to walk with caution and to think well whether it is good, whether it is to do so. When cleaning, there is a risk of spoiling the coin, although most of the time my coins were cleaned well and without any problems.

With the era of developing the capabilities of metal detectors, the treasure relocation experience another flourishing one. On the one hand, this led to the extraction of a sufficiently large number of coins, previously unusual rare foods tended to be. Now even 2 Kopecks in 1925 or 1927 are often designed for auction in such a way that they are in the presence of funds to buy them for collection. On the other hand, the copies of dignity are still low, as almost a century in the ground in the ground leaves the coin of indelible traces. How can you turn the black metal circle with the estimated date into something resembling a coin that will make fighting in auctions? This question puts the newly rented owner of the Rarite on the cleaning process. The same processes must be locked into place on those who have acquired an adequate collection.

Stage 0 - preview

Let's just say very loudly and clearly: Any cleaning will not be in the "UNC" coin.Even if there are no caves on the coin, and the field of coins will sparkle, the prototype of a collector or dealer instantly distinguishes from its native brightness, inherent in copies, what has just left the territory of the mint. The price of an open coin is much lower than the cost of its sister found in the "Crankeryted" category ("without circulation"). This is why the comments on the forums are so common: "You just cleaned half the cost of the coin." Beautiful patina for old coins is much more preferred for the unnatural shine after thorough cleaning.

When you have an expensive copy on your hands, you shouldn't undertake to clean it without sufficient experience. It is better to pay ten thousand from a specialist and get a coin that can start from a hundred thousand than to find an overcrowded piece of metal that even a newcomer does not want to put in the collection. Having two coins minted from the same metal is rare and common - it is worth cleaning the cleaning method on the ordinary coin first, and make sure that cleaning does not kill the coin or cause it significant damage.

At this point we take all coins from "Proof" - and with a polished money field. These cleaning coins are not subject. Any effect for them is detrimental. Examine the auction passages (you can use the base of our website) and you will see how the slightest shortcoming significantly reduces the price, and most sellers to abandon the acquisition of an instance of a less than ideal condition. If it seems to you that a little dark language can easily and simply remove, then remember the parable of the monkey who pulled the peas and the thoughtless pea. Trying to lift her, ten pulled her back. In an attempt to collect them, they scattered a hundred. In the same advance, the flaws in a polished coin will grow with the simplest cleaning. Yes, polished coins are cleaning professionals, but the process isn't closer to cleaning, it's closer to restoration (which we won't address here).

If polished coins are still not tolerated, please read the article on our website "How to Launder Money", which is dedicated to the economical cleaning of the silver category "Proof".

Stage 1 - soapy solution and rinsing

To remove the dried dirt, it is worth housing to clean the coins in the SOAP solution. It softens solid foreign funds on one coin. After a while, they will peel themselves off, or they will be easily removed without affecting the mint (which would not happen, try to hide the sleeping solid lump). The coins of the last century are mainly resistant to the water environment so it does not hurt in the SOAP solution. Of course, you shouldn't keep coins away from iron and other materials in water. If you don't want to check in a word, pour the water into the water using a handful of modern steel-based GRIVENS. Long term flesh in the water will hopelessly ruin them. But the brass coin can be in the water element long enough.

After being extracted from a solution, the coin needs washing. Specialists do not recommend using running water under the tap. Due to the chloride compounds in its composition after drying, you can see a slight RAID on some coins, which negatively affects the overall impression of the instance. So go through either distilled water or unpicked bottled water from the nearest store. Of course, if we have experience in cleaning brass or nickel in the last few years of the USSR, it is of course excessive expenditure exclusively, and conductive water is quite suitable for them. Inexpensive coins can be cleaned in parallel to washing with a soft toothbrush with non-abrasive paste. This process removes softening dirt from hard-to-reach places.

Rinse in distilled water with soap suitable even for coins in the state of "evidence" if you drop those precious copies in the dirt. Of course, the toothbrush is categorically excluded. After washing, drying is required. Drops of water are removed with a soft cloth or napkin. In addition, it's not a WOB, but the coin shots. That means you're just touching the surface and not chopping it in all directions. After marking, it is necessary to dry the coin near the heat source (for example, incandescent lamps). This does not mean that in order to save time, the coin should be made on the area of ​​highest temperatures that the heating grid will accommodate. At high temperatures, a valuable coin can be trusted or melted.

Level 2 - Chemistry: From a cheap to a favorite

Instance before starting cleaning

Plans and dreams collector * * * * * REFICAL REALITY at the end of the process

Experience to train on the cheapest copies that will not be sorry for later. At this point many illusions are broken. It seems that after cleaning the coin, the color simply changes from black or green to isophoned and is like on specimens dormant in museum shows. The result is the most common: an exuded mint of the bellows and the discharge misinflation. And all because patina does not fall outwards, but part of the coin itself. It smooths out irregularities and hides the flaws. I remove it, you press all the hidden defects. Sometimes dry cleaning disturbs almost all the relief, from the time to the patina, and we are no longer a coin, but a strange circle on which not to dismantle or digits or inscriptions.

Have you decided to clean? Make sure you determine which metal coin the coin is from. Ideal for a metal, the tool will irrevocably destroy others if they do not take into account the composition of the ingredients arriving at it. It is more difficult to clean the tin or lead from the coins. These are very soft metals. For them, both abrasive cleaning and erasing relief and most of the chemistry are contraindicated. However, aluminum coins are easily cleaned. The film formed on them quickly replaces the original brilliance of an unsightly torch. However, it is easily removed by simple composition (experts recommend 50 g of borane dreams, 5 grams of ammonia alcohol per 1 liter of water). After such cleaning, aluminum is not washed, but dried immediately.

Aluminum bronze and brass can be easily cleaned with modern kitchen chemicals. However, it should be remembered that chemistry is washed with copper, and the color of the golden brass coin turns pink or scarlet (newcomers, envious of such an instance, immediately pull it to put it under the guise of a rare copper probe to number). Therefore the experiments on cheap coins form their chemical series according to the degree of effect on the coin. First of all, try to fix the state of the case weaker and only after death to strong reagents.

Copper, after parting with a patina, acquires a sharp reddish hue. Therefore, it is therefore necessary to work with copper, either accept the coin or move to the next level of the basic skills of the collector - regardless of the patina that returns the coin to the usual chocolate color.

Level 3 - Silver family

Cleaning Darmeted Silver does not require any additional skills. Remember, however, that the silver state of "Evidence" should not be brought in the same way as cabin spoons or teaspoons that remain from previous generations. Otherwise, the coin will not be sold at the price of the catalog, but at the price of the metal price on the exchange. Working with ancient coins, in which other metals besides pure silver are also present, must be combined with the removal of oxides. If it's copper, the coin can be green. Here the recommendations of specialists do not agree, relying on their own experience. Someone uses a fifty composition composition of sulfuric acid, and someone is a decade of the forming composition with heating to seventy degrees Celsius. Where worse when the coin acquired a purple-gray hue. This is the so-called "horn silver". It follows, just to get rid of it in full, that there is a core of a healthy metal underneath. Here we are helping a ten-year percent solution of ammonia. After the gray-purple layer has softened, it is removed with a soft cloth.

Level 4 - gold, platinum and palladium

When the coin material belongs to this trinity of chemically inert metals, the task is simple and complex at the same time. Chemistry doesn't help here. Of course, with due diligence, you can get a reagent it learns, but it is better to do without it. Soapy solution and rinsing in water without chlorine. That is quite enough. Some before the sale to polish the coin. However, the unnatural brilliance with natural scratches is more likely to scare potential buyers rather than increase their numbers.

Level 5 - Specialized Liquids

A number of solid companies have long taken care of collectors who offer them a wide variety of cleaning products that can noticeably improve the appearance of the coin. In addition, there are products from small businesses on the domestic market and also have a positive effect on the appearance. When purchasing one or another product, it is necessary to read carefully for which metal (or groups of coins) it is intended, carefully read. Calculate the economic effect of their use. After all, by shopping for an expensive import tool and spending it integrating into an outline view of a pair of coins easy to buy for fifty at any auction, nothing but moral satisfaction you won't get. After trying a number of funds, you will also find that cleaning them sometimes does not save the coins from the defects received, but only masks them to the pore until time. As an example we show a bimetal tent.

Yes, after cleaning, dark divorces no longer spoil the appearance of a potential buyer. However, a picky collector may indicate that these divorces are going nowhere. However, they are still present on the edge of the ring, but in the high condition. This is further evidence that cleaning doesn't translate coins into the "UNC" category guided by the modern anniversary price tags.

In the following articles we describe in detail how in the room conditions an inexpensive coin can lead to a decent condition with the very easiest cleaning. You will learn about mechanical cleaning as well as why the Shabra is necessary. In the meantime, we hope that this little review will give you the original concept of purification coins and save you from incompetent actions that seldom spoil you.

How To Clean Coins At Home

Various metals and alloys are used to make coins, which are subject to corrosion and oxidation, which not only spoils the appearance of the product, but also reduces the cost of especially valuable royal, Soviet and anniversary instances. One such problem creates the question of how to clean coins and avoid damaging them at the same time.

Vintage coins have value for history. To maintain their primordial look, provide suitable storage conditions and conduct preventive cleaning regularly

Returning metal money displayable view and extending storage time will help Mechanical, chemical and ultrasonic cleaning methods . The choice of method depends on the type of metal, the type and degree of pollution. The article provides useful recommendations and the most effective methods to help maintain the purity of vintage and modern coins.

Features of cleaning products from different materials

When choosing a method and means of cleaning coins, the correct consideration is given to the material from which they are made. The right approach enables the brilliance to be achieved quickly and effectively without damaging it.

gold and silver
