Things You'll Need
Instructions
Gather the coins that you want to clean. Try to avoid handling the coins with your fingers if they are particularly dirty; use disposable gloves to keep your hands clean.
Soak the coins in soapy water in a plastic bowl for a few days to loosen dirt and debris. Agitate them every now and again by shaking the bowl to help break up dirt.
Rinse the coins in a colander in the sink under running tap water. Pat dry with a clean, soft cloth. Lay a soft cloth out on a flat, non-wood surface and gently empty the coins onto the towel to dry. Let dry for a few hours.
Repeat the above step if the coins are still dirty. If they aren't clean enough, put the coins back into the bowl, cover with vinegar and pour in 1/8 to 1/4 cup of baking soda. This will help remove any remaining dirt and grime.
