Bring the jewelry to a sink for easy access to water. If your jewelry pieces are very small, make sure the drain is partially closed before you begin.
Dip the toothbrush in warm water and add a dot of detergent. Gently brush all surfaces of the lacquered jewelry, including clasps and crevices.
Hold the jewelry under warm running water to rinse.
Pat dry with a soft towel.
Lay a clean towel on the counter top and spread the damp jewelry on it to dry completely. Leave the jewelry overnight for best results; putting it in a jewelry box while it is still damp could damage the finish.
