How to Clean Jewelry
Gently scrub the jewelry with a soft bristle
Scrub each piece of jewelry individually, paying special attention to nooks and crannies where dirt may be hidden. Use a very soft brush the softer the better. Stiff bristles can scratch the surface of your jewelry. If your jewelry is goldplated (as opposed to solid gold), especially stiff bristles can even remove the gold layer entirely!
Special brushes designed for this purpose are best, but most small, soft brushes (like, for instance, eyebrow brushes) will also work.
