The Brilliant Jewelry Cleansing Foam is excellent cleaner for all types of gold and platinum jewelry. It even works on fashion jewelry too! Simply drop your jewelry in the cap of the bottle, then pump some foam into the cap and let it soak for about 15-30 seconds. If your jewelry is very dirty, soak it for a little longer. Use the included brush to get in between the difficult to reach places and to loosen stubborn dirt or buildup. Rinse well with warm water and dry. For better results, use a Brilliant® Polishing Cloth to restore luster and shine. We can even private label bottles with your store logo which makes these cleaners a great giveaway or add on purchase!
