Jewelry Cleaning Warning
Ammonia is a good choice for cleaning jewelry, but tarnished sterling silver jewelry must not be soaked in the same jar or bowl as gold jewelry. If tarnished sterling silver jewelry is cleaned in any solution with ammonia, the used solution should NEVER be used to clean gold. If you do not follow these directions, the gold jewelry will become silver plated. You will have to bring it to a jeweler to remove the silver plating.
