coin cleaning with soap
Coin Cleaning
Clean
old coins in a weak soap solution.
If
the distilled water was too weak to effectively clean the surface of a dirty or
encrusted coin, the only other non-damaging option is to use a weak soap
solution. Pour a small amount of a weak liquid soap into a large bowl, and then
fill the bowl with tepid distilled water. Grasp your coin by the edges, and
swirl it around in the soap solution. Then rinse the coin under distilled water
and pat dry with a clean cloth
Do not use dish detergent to clean your coins, it’s too powerful and
abrasive. Instead use a weak, gentle soap, such as hand soap
