Instructions
Using a Lemon Soak
Soak the coin in a bath of lemon acid. How long you leave it soaking depends on how oxidized the coin has become. For a little oxidation, leave it soaking for a few hours. If severely oxidized, you may need to leave it soaking for a day.
Remove the coin and gently brush at it with a soft brush, like a toothbrush.
Rinse the coin and pat it dry with a tissue.
Alternative Spot Cleaning
Dip a tissue into warm vinegar or sour milk, as either of these will work as your acid solution.
Rub the damp tissue on small oxidation spots on your silver dollar coins.
Alternatively, cut a potato and rub the raw potato on the coin, using the acid from it.
Rinse the coin in water to clean off any acids, then pat it dry with a tissue.
