How to clean silver coins
If you’ve got a handful of old silver coins that have lost their glow, and are covered in years of tarnish and grime, then try the technique described below to bring back the lustre and shine. It works wonders and can take a “bottom of the drawer” coin and turn it into a showpiece.
What you’ll need:
DO NOT USE for collectible coins/numismatics..
- Some old, dull, junk silver coins
- Cloudy ammonia
- White vinegar
- Bicarb soda
This guide is for junk silver coins only. Cleaning collectible coins isn’t a good idea.
Wash the coins in warm water with dishwashing detergent, then pat dry.
Use your fingers to rub bicarb soda and plain white vinegar into the coins (it will fizz!). The fizzing bicarb will remove any dirt that the dishwashing detergent didn’t dislodge. Wash off in warm water and pat dry thoroughly.
Soak the coins in cloudy ammonia for at least 2 hours. Use gloves when working with ammonia, and make sure you’re in a well ventilated area. After 2 hours, remove the coins from the ammonia, rinse with water, and pat dry.
That’s it! Repeat if necessary.
