How to Wash Coins

If you collect coins, it is likely that you have several coins that are dirty or tarnished. It is also likely that you will have a desire to wash and scrub them, revealing the bright and shiny metal underneath. Before you dig through your cleaning supplies, keep in mind that many coins may be more valuable in their natural, tarnished state. However, if you are confident in your decision, there is a very gentle and effective way to clean your coins.

Things You'll Need

Coins
Mild dish-washing detergent
Distilled water
Two small containers
Toothbrush
Cotton towel

Instructions

- 1
  Determine the value of your coins before cleaning. Very old coins may be worth more if you do not wash or tamper with them, so buy a pricing guide or take them to a dealer to have them appraised.
- 2
  Wash your hands thoroughly to avoid transferring any dirt or oil to the coins.
- 3
  Run each coin under hot water for a couple minutes on each side.

  Soak coins in the solution for at least a few hours. For the best results, you may soak coins for up to two weeks.
- 6
  Remove coins from the solution and run under hot water once again.
- 7
  Wet a toothbrush with hot water and gently scrub the coin to dislodge any remaining buildup.
- 8
  Fill a container with distilled water and swirl the coin around in the container for a final rinse.
- 9
  Pat coins dry and allow them to air dry on a clean cotton towel.
