Things You'll Need

Instructions

1

Soak the coin in a container filled with either vinegar or grape oil (olive oil will also work). Use vinegar for silver coins, and grape oil for copper. The coin should be soaked until the dirt and corrosion have been dislodged.
2

Pat each side of the coin with another clean, dry cloth to help it dry. Avoid scrubbing, as this may damage the coin.
3

Rinse the coin using distilled water.
4

Set the coin down on a clean, dry cloth and let it dry. If you're cleaning multiple coins, they should be placed on the cloth without touching one another.
