It is important to read your warranties and ask questions at the time of purchase about the care and cleaning of your jewelry items. Due to the differing types of metals involved, extreme caution must be take in cleaning these types of items. Are they plated brass, copper, aluminum, bronze, tin, or some other metal? Are there stones in these items? Are they glued in? Specific cleaning instructions will vary with each manufactured type of item and stone. A general rule for cleaning would be the same as silver plated items: warm water and a soft cloth.
