Here is a link that works well on silver
http://gometaldetecting.com/electrolysis_coins.htm
Ues a 12 volt - 15 volt transformer ( from cell phone or battery charger etc.)
cut the ends and put stainless aligator clips on the ends
8 oz. glass of cold water and 1 tps baking soda or(salt and couple drops of lemon jucie)
Attach one clip to a stainless steel spoon and the end clip to the coin/ring)
use a close pin or bag clip to keep the cion and clip suspended in the water
5 min. - if the spoon bubbles more than the coin/ring switch the aligator clips (they are reversed)
Chemicals? - I use Wrights Silver Cream to polish
First put the cream on a rag and buff
then polish with the foam insert.
the rag will turn black
Copper and Nickle dosen't work so well -
