Before investing in any cleaning equipment � try the WATER
SOLUBLE (WS) polishing compounds. May purchase from Gesswein and
others. I have been using for some time and cleaning is no longer
a problem�. Ammonia and other stuff. Simple use any soap and warm
water with tooth brush. I use WS Graybar for cut-down and general
touch-up. Then WS RED rouge for finale polish My experience is
with Silver � gold should be similar.
Go with the flow
