Take Care of Your Rhinestone Jewelry
If your rhinestone piece of jewelry is not very dirty, you can clean it by very gently using a polishing cloth, or by brushing gently with a very soft old toothbrush. For dirty items, spritz the a soft bristle toothbrush with a diluted window cleaner [ie windex], tap the bristles until no moisture shows on your cloth, then gently brush the front of the item and blot with your lint free cloth. The back can be cleaned the same way, unless the foil-backed rhinestones are in open settings. If your rhinestones are not foil-backed no need for this precaution.
