Things You'll Need
Instructions
Wash the coins in warm soapy water and clean with a toothbrush to remove loose grime and debris. If a simple wash is all the coins need, buff them dry with a soft towel.
Place heavily tarnished coins in a saucepan and fill halfway with water.
Crumple a piece of aluminum foil and toss it into the saucepan.
Add 1 tsp. table salt and 1 tsp. baking soda for every quart of water in the pot.
Boil the coins for up to five minutes. You will know when to stop by looking at the coins to see how clean they are.
Remove the pot from the heat and drain the coins in a colander.
When cool enough to handle, buff the coins dry and restore the shine with a soft towel.
