Here is what I use for cleaning coins, etc., via electrolysis method. Use at your own risk. Consider testing with a junk coin first.
Suggested items used:
12 volt trickle battery charger
Baking soda
Small piece of steel
Water (Distilled or Reverse Osmosis)
Glass or plastic container
I mix 1 measured teaspoon of baking soda into 2 cups of water. Attach coin onto the (-) Negative (black) clamp of the charger and (+) Positive (red) clamp onto the scrap piece of steel. (I use a hardened concrete type nail, non coated.) Then place both wire clamps submerged with their appropriate attached objects into water mixture. Then plug charger in wall outlet. Unplug charger prior to inspecting coins, etc.
Check condition of coin after 15 minutes or so. I keep changing/replacing the water solution after each 15 minute interval. Don't go overboard with the cleaning times...check as you go along! Sometimes less is more.
