How to Clean Gold Jewelry Gold unlike silver does not tarnish and is easy to clean. You can clean most gold with a household dish soap like Dawn. Put a few drops of liquid dish soap into a bowl of warm water then soak the gold jewelry in the solution for 15 minutes. If you really want your gold jewelry to shine gently scrub the jewelry with a soft-bristled toothbrush with a drop of dish soap for a minute or two then rinse the jewelry under warm running water. Blot the gold jewelry dry with a soft cloth. Never clean gold watches or lockets in water unless approved by the manufacturer or approved by a professional jeweler.
