Cleaning coins from dirt is a responsible process. It is important to consider the metal from which the artifact is made, so as not to damage the product.
Coin cleaning is a process that removes dust particles, earths and traces of material oxidation from the product. The action itself is carried out using various means and tools. The most important thing in this process is to take into account the metal or alloy of metals from which this or that coin was made.
How to clean coins from oxidation and other defects
As mentioned earlier, it is important to consider the material from which it was produced when cleaning a coin. If the artifact is contaminated with particles of dust or earth, then the metal does not play a special role. It is only recommended to use warm water and a soft brush or toothbrush.
If the coin shows signs of oxidation, there are several ways to clean it. If a person has to cleanse a silver coin, then it is desirable for him to know the fineness of the metal. If the material has a sample of 625 and higher, then a solution of 10% ammonia is suitable for cleaning. For lower samples, a solution using lemon juice is suitable. Silver coins can also be cleaned with baking soda.
Artifacts created from an alloy of iron and zinc should be brushed with a mild hydrochloric acid solution followed by a brass brush. At the end of cleaning, it is recommended to wipe the coins with a piece of felt cloth.
