Copper cookware is now not only an item for daily cooking, but also a fashionable element in the interior, occupying a place of honor among kitchen utensils.

In the Norman village of Villedieu-les-Poels, the production of not only copper jewelry and decorative items, but also kitchen utensils began in 1830.

Copper is considered a unique material; if properly cared for, it is not subject to corrosion and has high thermal conductivity.

The inside of the dishes is coated with a special alloy - tinned tin, which prevents direct contact of the cooking products with the acidic environment.

However, the material still requires proper and timely care.

Decorative items made of copper require rubbing to a shine, and kitchen utensils in the form of pots, pans, stewpans, basins and turks should be regularly inspected and washed thoroughly to avoid an unpleasant gray-green coating, and sometimes rust.

Oxide on copper products mainly appears in areas subject to frequent heating.

To prevent this from happening, it is necessary to carry out regular preventive cleanings.

Some of the most commonly used folk methods are:

1. Mix flour, salt, vinegar in equal proportions, apply to the entire surface of the dishes, rinse with water and wipe dry with a towel;
2. add two tablespoons of table salt to one liter of vinegar, bring to a boil and immerse the copper bowl until completely cool, then rinse with water, rub with a napkin until shiny;
3. prepare “vinegar dough” from flour and vinegar, cover the entire surface of the copper until completely dry, then remove with a sponge;
4. crumpled newspaper will not remove stains and deposits, but will impart a radiant shine to the surface of the product.

Why do copper cookware need to be cleaned regularly?

Copper is one of the metals that can tarnish and oxidize.

For prevention, each time after using kitchen utensils, they must be thoroughly washed and wiped dry, and also avoid direct exposure to direct sunlight.

Regular cleaning will promptly eliminate the formation of plaque and the release of toxic substances.

This regular maintenance will extend the life of the copper.

How to clean copper?

Several modern means are considered the most effective and fast-acting:

1. Copper cleaning paste was developed by the cookware manufacturers themselves, who, like no one else, know all the intricacies of caring for such products. According to the instructions, just apply the product to a sponge and wipe the surface with dirt in a circular motion. Rinse thoroughly under water and rub with a towel;
2. gels are especially suitable for kitchen copper items. Eliminate traces of corrosion and oxidation products, degrease the surface. These products are also widely used in catering establishments. After applying the product, no additional rinsing with water is required;
3. rubbing wipes are considered one of the most gentle, but less effective methods. Without the use of additional products, they can only give a radiant shine.

How to clean copper from green deposits?

Green plaque on copper releases toxins and must be removed. Not all means can cope with its elimination.

There are several ways to remove corrosive plaque:

• The carbonated drink “Coca-Cola”, due to the presence of phosphoric acid in it, will clean and get rid of any contamination, especially green deposits. Pour this sweet fizzy drink into a small glass container and place a pot or frying pan in it for several days. This is a very original and at the same time effective method;
• ethyl alcohol mixed with turpentine and oxalic acid will also cope with green plaque. It is enough to saturate a soft sponge or rag with this liquid and apply it to the contaminated surface;
• Apply white chalk mixed with kerosene to a mushy state to the area of ​​contamination or plaque formation. This is a great way to rub and add shine to a copper piece.

How to clean copper utensils from blackness?

Black plaque is also considered toxic. Requires mandatory elimination. However, such kitchen utensils can no longer be used for cooking.

To help get rid of blackness:

juice from half a lemon will remove the blackness if you rub it on the product, then rinse under the tap and wipe dry. If you don’t have lemon at home, you can replace it with citric acid, diluted with water to a paste.

hot soap solution diluted in a container. It is enough to immerse the dishes in it for a short amount of time. Then rinse lightly under running water and wipe dry.

with an ammonia solution . This procedure only needs to be carried out with caution, always in the open air to prevent poisoning from ammonia fumes. It is enough just to wet the sponge and wipe the product with it.

How to clean copper dishes from white deposits?

The white coating formed due to oxidation must be removed.

Several proven and reliable methods will help you quickly deal with it:

Tomato paste or ketchup, due to its high acid content, is good to use to remove white deposits and to give copper a reddish tint. It is enough to mix two tablespoons of paste with one tablespoon of salt and apply the resulting mixture to the product for 10 minutes with a sponge. Then rub in a circular motion over all the outer walls, remove the residue with a paper napkin.

glass of any fermented milk product , it is best to use sour milk, mix with 1 tablespoon of salt, soak a piece of flannel cloth or microfiber cloth with the resulting mixture. Rub the surface until the white coating is completely removed.

amidosulfuric acid , used for heavily ingrained plaque. When using it, it is important to follow safety precautions. This powder is quite aggressive, but quickly cleanses and adds shine to copper.

Mechanical cleaning of copper products

This type refers to professional cleaning and involves pre-soaking in distilled water. Then it is carefully impregnated with synthetic resin to strengthen the patina and prevent scratches during further cleaning.

Craftsmen use needles, brushes with minimal rigidity, manual and mechanical scrapers with different tip shapes, as well as metalworking tools.

This process is considered very long, painstaking, requiring patience and care.

Precautions when cleaning copper

When cleaning with aggressive agents, safety precautions must be observed:

• read the instructions carefully;
• use rubber gloves;
• if necessary, wear a protective mask to avoid burns to the respiratory tract caused by cleaning agent vapors;
• when mechanically cleaning copper, use plastic goggles to protect your eyes from foreign bodies;
• in case of contact with the skin or eyes, immediately rinse the area with water or seek medical attention;
• To avoid damage to copper, it is not recommended to leave the product in acid for a long time, and also to use iron brushes and abrasive substances.

Caring for Copper Cookware

There are several rules for the care and preservation of external and internal coatings:

• store dishes only in a dry cabinet, as humidity and heat contribute to the process of destruction and blackening;
• cannot be washed in the dishwasher, even at minimum temperature;
• do not keep empty dishes on a working stove;
• To avoid scratches, it is advisable to use wooden or plastic kitchen utensils;
• abrasive detergents containing chlorine, as well as metal brushes or sponges, are prohibited;
• Copper cookware does not like sudden temperature changes, so pouring boiling water into it is not recommended;
• food containing a large amount of acids, for example: vinegar, fruits or tomatoes - it is better to put them in another container.

The healing properties of copper have long been proven, but time has not been kind to it. Therefore, only with proper storage, cleaning and care will such dishes last a long time and delight you with their incredible color and radiant shine.

How to clean copper at home: ways to clean copper products with different means

How to clean copper? The relevance of this issue is explained by the fact that products made from this metal have been used by humanity for many centuries. For a long time, the value of this metal was so high that it was equal to gold. The development of technology has led to the fact that it was possible to significantly reduce the cost of copper production.

This made it possible to make not only jewelry from this metal, but also dishes and interior items. The high popularity of this metal and alloys based on it is explained not only by its decorative effect, but also by its unique characteristics - high ductility, thermal conductivity, corrosion resistance, etc.

No one wants to use oxidized copper cookware.

Why copper products need to be cleaned regularly

During use and storage, copper products become covered with a dark or green coating. The oxide film is formed as a result of the interaction of the metal with atmospheric oxygen. Heating or using the item outdoors or in rooms with high humidity accelerates plaque formation. At the same time, dishes and decorations lose their appearance and look untidy. In the sailing fleet, most of the metal parts of the ship were made of copper, and there was even such an expression as “scrubbing a piece of copper.”

In addition, the chemical compounds that make up plaque can have harmful effects on human health. Therefore, copper products must be cleaned regularly.

Copper oxidation

Since ancient times, people have been improving cleaning methods, using both mechanical and chemical methods.

Cleaning a Turk, samovar or kettle

The exterior of this kitchen utensil can be cleaned using any of the suggested methods. The inside is much more difficult to clean. There, objects are oxidized by water, but also covered with a lime layer.

To remove dirt from the inside, potato peelings are used. They are placed in a bowl and poured over with boiling water. Then set the utensils on the fire and boil the cleaning for an hour. Then the contents are poured out, and the utensils themselves are washed in heated water with detergent.

To complete the cleansing, boil plain water several times in a cleaned container. This gets rid of traces of limescale.

Effective cleaning methods

Today, the arsenal of tools that can be used to clean copper has expanded significantly. Together with ancient vinegar, sand and wire sponges, a large number of both specially designed products and those adapted by folk craftsmen are used. Among the latter there are some quite unexpected ones.

How to clean copper

• Tomato ketchup. Apply a small amount of tasty seasoning to the stain and leave for several minutes. Rinse off with plenty of water.
• In case of light stains, you can try washing them with a regular gel detergent. The gel is squeezed onto a soft sponge and then applied to a copper object. After leaving for a minute, rub the surface and rinse with water.
• Used for large products, such as a samovar. Cut the lemon in half and rub the half over the surface of the product. Next, clean with an elastic fluffy brush and rinse with water.
• Vinegar dough. Mix vinegar and regular table flour in equal parts. Stir until a homogeneous paste-like mass is obtained. Next, the paste is spread in a thin layer on the surface to be cleaned. After waiting for complete drying, remove the product with a rag or wooden spatula. The product must then be polished with a soft cloth.

If the above methods do not lead to success, use the following method:

• Prepare a stainless steel basin or pan.
• Pour vinegar and add a couple of tablespoons of regular table salt. Stir thoroughly.
• Immerse the item to be cleaned in the solution and bring to a boil.
• Remove from heat and leave to cool at room temperature.
• Drain the cooled solution, rinse the copper object and wipe dry.

Cleaning copper with vinegar

If you decide to clean copper, take precautions. The use of protective gloves and glasses is mandatory. If you dilute vinegar essence, you should ensure ventilation of the room.

Effectively cleaning copper coins

Previously, small coins were made from a copper alloy. Today they are considered a rarity. Since a film often forms on the surface of coins, this reduces their value. To remove oxidation and return items to their original appearance, antique dealers use industrial cleaning products. With their help, you can not only return coins to their original condition, but also clean a copper pot or an antique basin.

Ways to clean copper at home:

1. A pronounced yellow coating on coins indicates contact of the products with a lead surface. Such items can be treated with acetic acid solution.
2. Citric acid powder will help remove the bright green film.
3. Remove red deposits with a liquid containing ammonia.

Before cleaning a copper basin, dishes or coins that are considered rare, you need to study the recommended treatment time and the amount of active substance. If you overexpose a copper object in Trilon, acid, or rub it with sulfur ointment in excess, you can ruin antique items.

Boiling coins in soda solution

Baking soda and copper interact effectively with each other, returning the shine to metal products. To prepare the solution, take 1 liter of water and 10 tbsp. l. baking soda. You will also need a small saucepan and an old toothbrush.

The solution should be poured into a container and the products should be lowered into it. They should be covered with at least 2 cm of the solution. Place the pan on the fire and boil the contents for 20-30 minutes. Then you need to let the coins cool. Already cold products are treated with a toothbrush, removing remaining dirt.

Trilon B

Trilon B is another option for processing copper at home. This is a ready-made chemical mixture that is sold in jewelry stores. It is designed specifically for copper surfaces, does not destroy the metal, like some acids, and carefully cleans it of oxide.

Metal products are placed directly into a jar of the substance using plastic tweezers for 10-20 minutes. Then they are taken out and washed. If the oxide layer is too thick, the procedure will have to be repeated several times.

Kefir, vegetable oil

Kefir contains non-aggressive acids that gently clean the copper surface, leaving a light patina. To carry out the manipulation, all items should be placed in glass containers and filled with fermented milk product. Keep copper products in kefir for 50-60 minutes. Then you need to take them out, wash them under running water and dry them.

When using vegetable oil, you need to additionally take dishwashing detergent, a deep saucepan and plastic tweezers. Pour sunflower or olive oil up to 2 cm high into the bottom of the container and boil. Using tweezers, lower the coins into the pan and keep them on the fire for 10-20 minutes. Then remove the copper products, rinse with dishwashing detergent, wipe and dry.

Citric acid, vinegar

Dark stains on ancient coins can be easily removed with vinegar. First, prepare a solution with 0.5 liters of water, 1.5 tbsp. l. 9% vinegar and 1.5 tbsp. l. rock salt. Copper objects are dipped into the liquid and sent to the fire. It is advisable to boil the coins for 5-10 minutes, then remove them, rinse and wipe dry with cotton cloth.

If desired, vinegar can be replaced with citric acid or freshly squeezed juice. If lemon is used, the fruit should be cut in half and the pulp should be rubbed onto the copperware. Leave them in this state for 10-15 minutes, then rinse under running water.

Cleaning copper at home

Copper utensils and jewelry should be cleaned regularly. With regular care, copper cleaning is carried out by regular washing or wiping with kitchen or sanitary gel. If plaque covers a significant area and cannot be removed by simple means, more radical cleaning methods are used.

How else can you clean copper?

• Citric acid powder is diluted at the rate of a tablespoon of acid per liter of water. Add a teaspoon of table salt and stir thoroughly. Use the resulting solution to wipe away plaque stains using a sponge or cloth. The method is convenient for items that do not fit in the sink: large figurines, door and window fittings, samovars, teapots, etc.
• Black deposits should be cleaned with ammonia. If you have to clean dishes, be sure to thoroughly rinse the utensils with plenty of water. If ammonia enters the human body, it can lead to serious poisoning. In the case when individual stains merge into a continuous layer of plaque, it is better to soak the entire product for one to three minutes.
• It is better to clean red stains with an ammonia solution with a strength of no higher than 10%. Carefully! Ammonia is poisonous. Be sure to provide adequate ventilation.
• It is good to clean yellow and black stains with a mixture based on regular 9% vinegar. To one part vinegar, take one part salt and two parts water. Immerse the item to be cleaned in the tank with the solution and bring the mixture to a boil. Carefully monitor the disappearance of stains - as soon as they have dissolved, stop boiling and allow the tank to cool. Next, the product should be rinsed with plenty of water and wiped dry.

Before you begin cleaning the entire copper item from oxides, you should test the effect of the cleaning composition in an inconspicuous place or in a small area.

If the product is effective and does not damage the surface, you can clean the entire product.

What is copper?

Copper is a ductile, but at the same time durable metal of a reddish-brown color. It is one of the main elements of the periodic table. The copper-based alloy is used to make other metals such as bronze and brass.

The scope of application of this metal is extremely wide. Due to its strength, it is in great demand in construction for the manufacture of wires, fittings, copper mesh, wires and other things. In the agricultural industry, copper is used as part of copper sulfate. Most wind musical instruments are made from copper. This metal is also widely used in the creation of plumbing pipes.

Despite the fact that copper is not a precious metal, it is also in demand in jewelry. You can find a lot of beautiful and very elegant copper jewelry: bracelets, crosses, chains, earrings, rings, etc. Also, to make gold jewelry more durable, an admixture of copper is used.

Copper cezves (Turks) have long become a popular accessory for lovers of delicious coffee.

Products made from this metal can often be found in the kitchen. Due to its resistance to corrosion and good heat conductivity, copper is used to make a huge variety of kitchen utensils: , etc.

How to clean copper from green deposits and dirt

Copper is a fairly soft metal that loses its attractive shine over time. Unfortunately, it is impossible to overcome natural oxidation processes. But it is possible to provide copper products with favorable operating conditions and timely cleaning. And then they will regain their original shine and serve their owners for many years.

Why do copper products need to be cleaned regularly?

When air and moisture come into contact, a film forms on the surface of the copper. It must be cleaned, because this coating not only spoils the appearance of the product, but can also be unsafe for humans.

Plaque on metal forms for two reasons.

When oxygen and copper interact, a chemical reaction occurs that causes the metal to oxidize. At the first stage of oxidation, copper changes its color to purple with a reddish tint. If the deposit is not cleaned off, the oxide will subsequently turn black.

Plaque on a copper product

When copper is left in a humid environment for a long time, a dense green coating forms on the metal - this is the so-called hydroxyl film. Copper hydroxide is poisonous. You cannot eat from dishes that have such a coating. You need to take precautions and remove the film.

Also, copper products may develop a white coating or rust.

Effective Copper Cleaning Methods

Before using various methods to clean copper, wash the product in warm soapy water or dishwashing liquid. This will help remove minor dirt, dust and add shine. If after the procedure the surface remains unchanged, proceed to cleaning using one of the methods convenient for you.

Copper cookware should not be washed in the dishwasher. It is preferable to wash and clean by hand.

Vinegar with salt

They cope well with thick layers of plaque. To clean, pour 9% vinegar over the plaque and sprinkle with finely ground salt. After 10 minutes, wipe with a cloth and rinse.

Cleaning copper with ammonia

Cleaning copper with phosphoric acid

To clean copper from rust, phosphoric acid is used. The product is dipped in a 15–30% solution of orthophosphoric acid and applied with a brush or spray. Leave for a few minutes to take effect. Clean off plaque with a cotton cloth. If necessary, repeat the procedure.

Cleaning with ketchup

This unexpected solution has proven itself in cleaning copper products from black deposits. Apply a generous amount of ketchup or tomato paste to the metal. Leave for an hour and wipe with a cotton rag. The fruit acids contained in tomatoes will not only get rid of plaque, but also restore the brightness of the metal.

Cleaning with salt and lemon

Squeeze the juice of one lemon. Add salt until a paste forms. Using a cloth or toothbrush, clean the surface of the copper to remove any dirt.

Using Baking Soda

Baking soda is one of the popular substances for cleaning metal objects. When cleaning with baking soda, copper products regain their lost shine.

Vegetable oil

Vegetable oil fills microscopic cracks in metal. Thanks to this, the product looks smoother, gaining a natural shine.

Use of chemicals

In addition to regular household cleaning products for cleaning copper, you can purchase specialized preparations at a jewelry store. They are good because they carefully clean the metal without damaging it. Such drugs include Trilon B.

How to clean copper products until they shine?

The choice of cleaning method depends on the degree of contamination and the type of product that needs to be treated.

Cleaning copper from white deposits

White spots on copper are also formed due to oxidative reactions. They usually appear on products made from alloys of copper and other metals. One of the presented methods will help against this kind of contamination: using ammonia, vinegar with salt or ketchup.

How to clean copper from black and green deposits?

Ammonia can deal with black and green deposits. You can also remove the toxic layer with a mixture of turpentine, oxalic acid and vodka. The ingredients are mixed in equal proportions and the copper products are cleaned with it using a cloth.

Cleaning copper from rust

To renew rusty copper products, use aggressive acids such as hydrochloric acid. Apply acid to a piece of cloth and treat the copper with it. After treatment, rinse thoroughly to remove any remaining aggressive substance.

When working with acids, be sure to wear gloves. And clean only in a well-ventilated area.

How to clean copper oxide?

To remove oxide in the form of a reddish coating, place the product in a 5% ammonia solution or ammonium carbonate. Hold until the plaque begins to come off.

How to clean a copper pot inside and outside?

The outer surface of the Turk can be cleaned using any of the methods presented above.

If you do not have experience working with aggressive chemicals and acids, use accessible and safe methods.

On the inside of the Turks, it is recommended to use softer substances so as not to damage the coating. For example, soda or ketchup.

How to clean tinned copper?

During the tinning process, a thin layer of tin is applied to the inside of copper cookware. Tin is a soft metal and must be cleaned with care.

Do not use sharp objects or harsh abrasives.

To clean a tinned copper product, you need to wash it with dishwashing detergent. Severe dirt is removed point by point with a soft brush or fine steel wool, previously soaked in vegetable oil.

How to clean a copper samovar?

The copper samovar is an antique item. Therefore, it is especially important to preserve its appearance and extend the service life of an antique device.

To clean a copper samovar, take salt, vinegar and flour in equal proportions. The ingredients are mixed and applied with a sponge to the outside of the samovar.

After treating the entire surface, remove any remaining cleaning agent with a dry cotton cloth. To make the surface shiny, wipe it with lemon.

If there are deep stains in the samovar, they can be removed with kerosene. Soak a cloth in the mixture and wipe particularly dirty areas.

How can you clean a brass samovar?

Brass is an alloy of copper and zinc. Aggressive chemicals and abrasives can damage the surface of such a samovar.

For safe cleaning, use oxalic acid. It must be diluted in 1 liter of water, applied to the surface of the samovar and left for 5 minutes for the reaction to occur.

Afterwards, the solution is washed off and the surface is wiped with a sponge soaked in soda solution to neutralize the acid. Rinse the product and wipe dry.

Clean a copper basin at home

As a rule, a copper basin is used to make jam. Such dishes have good thermal conductivity, antiseptic properties, are safe for humans, and when cooking the jam practically does not stick to the walls.

If the jam is still burnt, the copper basin can be cleaned with vinegar dough. For this ancient method, you need to knead the dough by mixing flour and table vinegar. Next, the dough is rolled out thinly and placed on the dirt.

After the mixture dries, carefully remove it. The vinegar paste absorbs dirt, making the surface perfectly clean.

Cleaning Copper Coins

Antique copper coins often have high antique value. Therefore, it is important for every numismatist to know how to clean a coin without damaging it.

"Trilon B"

This special chemical mixture can be purchased at jewelry stores. It does not destroy the surface of copper products and carefully cleans them of oxide.

Dip the products into the solution and hold for 10–20 minutes. In case of severe contamination, the procedure can be repeated.

Kefir and vegetable oil

Kefir contains non-aggressive acids that gently cleanse copper. Place coins in fermented milk product for 1 hour. Then rinse with running water and dry.

Vegetable oil also gently cleans coins, filling small cracks and giving them a natural shine. Pour 2 cm of oil into a pan and boil. Using tweezers, lower the coins and boil them for 10-20 minutes. Then rinse the items with dishwashing liquid and dry.

Citric acid and vinegar

Vinegar will help remove dark spots on old coins. Dilute 1.5 tbsp in 500 ml of water. spoons of vinegar (9%) and salt. Dip coins into the liquid and put on fire. Boil for 10 minutes, rinse and dry.

On a note. Instead of vinegar, you can use citric acid or freshly squeezed lemon juice.

How not to clean copper products

In order to preserve the shine of copper products for a long time and not scratch their surface during cleaning, you must not:

• use abrasive materials and hard metal objects;
• subject to constant exposure to humidity;
• remove the varnish layer, if there is one on the product;

How and with what to clean copper? Review of 5 simple methods, video

Copper products are quite common in everyday life. These can be not only coins or antique decorated items, but also kitchenware and other utensils. Their luxurious look fits perfectly and transforms any interior.

However, the impression can be spoiled due to the unpresentable appearance of copper objects due to the formation of an oxide film on their surface, giving the metal a dull green tint. Therefore, the question of how to clean copper remains relevant for many owners of such trinkets.

Why does copper require regular cleaning?

Timely care of copper utensils and other products is of no small importance. This is due to the darkening of objects and the appearance of an oxide film on them. Oxidation occurs most in those metals that are often exposed to high temperatures or are exposed to open air for a long time. Thus, copper pots or plates that are constantly used in the kitchen quickly acquire a dark shade. Only cleaning will help them.

With copper jewelry the situation is the opposite. They may darken over time and then return to their original shiny state. There is an opinion that the appearance of copper jewelry reflects the state of health of its owner.

But this factor is primarily associated with constantly changing environmental conditions: humidity, temperature and pressure. However, some representatives of alternative treatment prescribe copper bracelets to their patients to strengthen their well-being and improve the performance of the cardiovascular system.

Copper utensils came to us from ancient times and continue to remain at the peak of popularity. This is due to the increased thermal conductivity of copper, due to which food in pans made of this metal remains warm for a long time. However, its constant use is fraught with darkening and loss of characteristic shine.

If you do not regularly clean copper and utensils from oxides, this can become hazardous to your health. The metal will begin to release toxins, so you will not have to use the kitchen utensils for their intended purpose.

There are several ways to clean copper coins at home, the choice of one of which depends on the color of the coating on the metal surface:

• If the surface of the copper is covered with a yellowish coating, then it is better to clean it with a 9% vinegar solution. You can prepare this solution yourself: you need to mix 1 part vinegar and 9 parts water. After the plaque has completely dissolved, the coins should be removed and washed under running water.
• It is quite possible that there is a reddish coating. It is better to remove such contamination by dipping a coin in a 5% solution of ammonia or ammonium carbonate. It is better to buy them in specialized stores. As the coin itself is cleaned, the solution will turn red. When the coating is completely removed from the surface of the copper, the coins are removed from the container with the solution, washed and dried with a napkin.
• Greenish patina is best washed off with a 10% citric acid solution. The same phenomenon will be observed here as in the previous cleaning method. As soon as the solution turns a characteristic green color, the coins are taken out, rinsed thoroughly in running water and dried.

Cleaning Copper Coins

Coins made of copper are no longer issued in our time, and many such products in the hands of the population are of antique value. That is why the question of how to effectively and at the same time carefully clean such coins is quite relevant.

You can restore the former attractiveness of copper coins using several methods. The choice of each of them depends on the nature and degree of contamination. So, depending on what color the plaque has formed on the surface of the old copper coin, you can clean it using one of the methods listed below.

• If there is a yellowish coating on the surface of the coin (this indicates that it has been in contact with a lead product), then it should be cleaned with a 9% vinegar solution.
• Clearly green plaque is cleaned with a 10% citric acid solution.
• Coins made from copper may also have a reddish coating. Such a coin is cleaned by dipping it in a 5% ammonia solution or ammonium carbonate.

Old coins made from copper may have a layer of patina, which gives them a more noble and aged appearance. If there is no such plaque, you can create it yourself, even at home. To do this, use a solution consisting of a liter of distilled water, 50 grams of copper sulfate and 5 grams of potassium permanganate.

The resulting solution is heated over low heat, without bringing it to a boil, and then coins are placed in it, which must be covered with a layer of patina. They are periodically turned over, and when the color of their surface acquires the desired shade, they are removed.

To consolidate the effect obtained, the surface of completely dried coins can be treated with benzene and alcohol mixed in equal proportions.
