Fast & Easy Coin Cleaning

This Instructable will show you a fast & easy way to clean coins.

Materials Needed:

  • Dirty coins
  • Electric Oscillating toothbrush
  • Baking Soda (Sodium Bicarbonate)
  • Lemon juice or white vinegar (optional for soaking)
  • Plastic container - large enough for all coins (optional for soaking)
  • small plastic container - to hold the baking soda
  • Paper towel or cloth (for drying)

Step 1: Soak Dirty Coins

This step is optional but does help in making it easier to remove the dirt / grime.

  1. Place dirty coins in plastic container
  2. Pour lemon juice (or white vinegar) into container just enough to cover the top of the coins
  3. Let soak for ~1 hr swirling solution every 15 minutes

Step 2: Scrubbing Dirty Coins

  1. Remove coins from soaking solution
  2. Pour some baking soda into the small plastic container
  3. Wet the tip of the electronic toothbrush and dip into the baking soda, so there is a paste consistency on the toothbrush head.
  4. Hold a coin between your fingers & turn on the toothbrush to clean each coin using the fast oscillations of the electronic toothbrush.
  5. Rinse off the coins & place on paper towel (or cloth) to dry
  6. Repeat 3 - 5 as needed for each coin.

    What, I'm the only one concerned about getting your toothbrush this grubby?

    I agree that cleaning "valuable" coins reduces the value that's why I chose non-valuable coins, but probably a good idea to note something in the Instructable that cleaning older / more valuable coins should be done with discretion.

    Cleaning old coins reduces the collector value, but this would be fun to do with coins that are really grubby. Even with a cleaned coin, if it's silver (1964 and older) you still have the silver value. Thanks for the tip.
