Silver coins can be cleaned by dipping the coins in lemon juice for a certain amount of time and then cleaning them with a soft brush. Afterwards, the coins should be washed using water and then dried off.
- Prepare the lemon juice
Take a small bowl, and squeeze the juice out of several lemons until there is a considerable amount of lemon juice. Lemon juice contains 5 to 6 percent citric acid, and it is this acid that cleanses the silver coins.
- Add some iron nails
Add some iron nails to the lemon juice before putting in the silver coins. Adding iron nails to the lemon juice is not essential, but it accelerates the cleansing process.
- Immerse the silver coins in the lemon juice
Put the silver coins in the lemon juice, and leave them submerged for a certain period. If using only lemon juice, leave the coins for several hours to a maximum of one day. If iron nails are added with the lemon juice, then leave the coins in the lemon juice for a maximum of 30 minutes.
- Clean the coins
Remove the coins from the lemon juice after soaking for the necessary amount of time, and clean them using a soft brush. After cleaning them, wash them with water. Then, dry them off. If the coins do not reach the desired level of cleanliness, then repeat the process.
