How to Clean Nickels

Coins minted and circulated in the United States change hands frequently. The natural oils from your hands build up on all surfaces of the coin. The oils combine with dust, dirt and other forms of debris, making the coins look darker and rougher than they actually are. Cleaning older coins is at the center of a contested debate in coin collecting circles, as it is possible to damage the coins with improper cleaning.

Things You'll Need

Petroleum jelly
Cotton swab
Small bowl
Dish soap
Towel
Toothbrush
Soft cloth
Ammonia

Instructions

- 1
  Rub the nickels with a cotton swab coated in petroleum jelly. The petroleum jelly loosens any dirt stuck to the nickels without harming the coin.
- 2
  Pour warm water into a small bowl and add a squeeze of dish soap. Stir the mixture with your hands, until the soap mixes with the water forming suds.
- 3
  Cover your work station with a towel and lay the nickels on top. Drop the nickels into the soapy mixture and let sit for several minutes.

  Dip the toothbrush in the soapy water, saturating the bristles. Remove the nickels from the water and place them on the towel. Rub the nickels with the toothbrush, using a circular motion. Wipe off the nickels with a second towel.
- 5
  Check both sides of each coin, looking for any stains or dirt. Mix 3 parts ammonia with 1 part water and use the toothbrush to scrub off any stains. Dry the coins with a soft cloth.
