Before cleaning copper coins at home, prepare a soapy solution. Dissolve the shavings of ordinary laundry soap with hot water (1 to 8) poured into a basin or other metal container. Coins are placed in this jelly-like solution and kept for ten days. From time to time it is necessary to heat the container with water, while not bringing it to a boil.

To do this, take seven parts of plain water for three parts of acid. To clean the greens, the coin must be placed in the solution for 10 minutes. As a result of a chemical reaction, the product will be cleaned and all the dirt will float. In this case, a shade of pinkish color may appear, which will disappear after a few weeks. At the end of the procedure, the copper object is washed with soapy water, which contains alkali. This is necessary to stop the acid on the metal. With strong oxidation, the procedure may be repeated.

Small specimens can be cleaned with oil. For this purpose, petroleum jelly is most suitable. Before you clean an old copper coin, a container of oil is placed on the tile. To clean a coin, it is placed in a boiling oil liquid over low heat. In this way, they quickly get rid of stains, rust and oxides on the collector's item.

Handy tools for cleaning copper products

If necessary, a rather large piece of home decor can be cleaned of green plaque - its entire surface should be rubbed with half a lemon, since the large size will not allow it to be put in any container. After that, you need to wait a while, about five minutes, and rub the surface with a brush, and then rinse with water.

This method is great for cleaning copper chandeliers, lamps, plumbing at home, because you can easily and easily get rid of traces of oxidation on the surface of products.

If it is necessary to clean copper dishes from any contamination, then you should be aware that copper that has turned green or gray, can be quite toxic and therefore you should not eat food from such dishes. After all, this can cause serious harm to health. So if the dishes are nevertheless covered with a green coating, then it is better to leave them as a home decor item.

But before that, it will have to be cleaned. To do this, you just need to place such dishes in hot water with the addition of baking soda to the detergent, then you need to rub it, and then rinse it in clean water. This method will help you quickly and efficiently clean copper products without much time and effort.

How to restore copper to its noble patina

Many methods of cleaning coins, together with oxides and dirt, also remove the natural patina, which is so highly valued by coin collectors. In order to artificially recreate it, you will need sulfuric ointment. It can be purchased at the pharmacy.

Left side with patina, right side cleaned of it

Sequencing:

• pour warm water into a small bowl or bowl;
• put on rubber gloves;
• apply and rub sulfuric ointment into the coin, you need to do this with your hands under water;
• try to evenly distribute the ointment over the product;
• as soon as the metal begins to darken, the product must be removed and wiped with a paper towel;
• leave the coin for two days to consolidate the effect;
• then grease with petroleum jelly and polish with a felt cloth.

The desired effect is achieved in several doses, with an interval of two months. It should be remembered, however, that artificial patina can be easily washed off with an acid-containing agent.

Why you need to clean regularly

The need for constant cleaning of copper objects arises from the fact that a dark coating and an oxide film quickly develop on the surface. Products that are heated or used in open air conditions oxidize especially quickly. Frequent use of products made of metal causes tarnishing and blackening.The external state of jewelry made of this metal depends on external factors with which there is a regular interaction.

Copper cookware, in the absence of cleaning, begins to emit harmful toxic elements. In this case, you cannot use the kitchen utensils for cooking. If all available methods fail to wash the dishes, it is better not to use them for their intended purpose in order to avoid negative consequences.

Cleaning coins with soap

Soap is a fairly mild cleaning agent that has little or no effect on killing a coin. We need to make soapy gruel. To do this, we are looking for a bar of soap, which contains EDTA (Ethylenediaminetetraacetic acid). This is our cleaning agent that will remove oxides and dirt from the coin. We rub the soap on a grater or chop it with a knife, dump it into an unnecessary container and fill it with warm water to make a porridge. Stir to a homogeneous consistency and throw coins into this business, previously washed under a tap with a brush.

The time during which the coins will be cleaned depends on the amount and nature of the oxides. For example, you can wait a month, or two, or even six months. It is better to take out coins once a week and rub them with a cut-off toothbrush under running water.

As I wrote above, the disadvantage of this method is the long cleaning time. Soap is almost incapable of affecting the metal of the coin. but if you overexpose the coin, the patina can come off, as it is also an oxide. In theory, having arrived from the cop, you can immediately throw coins into a bowl of soap.

By the way, I strongly advise you to cover this whole thing with a lid so that the soap does not dry out and does not lose its activity. I will also say that if the relief of the coin rests exclusively on oxides, later only a bald round will come out of the porridge. If such specimens are of any value, it is better to clean them mechanically.
