How to Clean Coins With Mineral Deposits

Through circulation, coins can amass a great deal of dirt and grime. Mineral deposits are among the many problems that collectors may face when seeking out pristine pieces. However, you can remove not only mineral deposits, but other types of dirt as well. Keep in mind that very valuable, antique coins should be taken to a professional for cleaning.

Things You'll Need

Water Liquid soap Toothbrush Distilled water Nic-A-Lene

Instructions

- 1
  Wash the coins in warm, soapy water. Scrub the coins gently with a soft toothbrush. Rinse each coin when you're finished. This may do the trick for very minimal damage. If not, proceed to the next step.

  Soak the coins in distilled water. The theory behind this practice is that the distilled water is "hungry" for minerals and will pull them from the deposits on the coins. You will need to change the water daily and repeat the process several times. Gently scrub the coins before placing them in fresh water to remove any loose deposits.

  Consider using Nic-A-Lene (see Resources) if you find that your coins are still not clean enough. This solution will remove any remaining deposits on the coin very effectively. Apply a few drops and scrub off with a brush. The reason that Nic-A-Lene is a last resort stems from the fact that this solution will also remove the coin's patina. This can be very detrimental to ancient coins, and you may want to take your coins to a professional before you attempt this step.
