[QUOTE="DrDuck, post: 596239, member: 158"] I've got an Aldi one, and find it most useful to clean the wife and girl's jewelry. Warm water with a bit of ammonia does the trick. The back of diamond and sapphire rings can pick up a lot of grease and dirt and remarkably affect the brilliance of the gem, so it is worthwhule It will remove dirt from a coin, but not do much about humic and fulvic acid and other soil stains.
