This cleaning product contains 100% natural products without acid. This allows you to start cleaning and remove the encrusted layer. Easy to apply with, for example, a cotton swab or by dripping a small amount of liquid on it.
There is no risk of a well-formed patina. The caked layer forms a kind of paste during cleaning. The operation must be repeated if the dirt layer is really too thick. As soon as the maximum amount of dirt has disappeared, it is wise to clean the coin with pure water (do not rub) and then let it dry and continue with, for example, chemical cleaning.
NB:
This product is only intended for cleaning. To protect the coins, use, for example, paraloid 44 or antique wax.
