Body oils can actually protect sterling silver and lessen how often you must clean and shine it. On the other hand, cosmetics, perfume, and hair spray can damage it. Try not to apply these products to areas where you will be wearing your jewelry. If this is unavoidable, spray the product onto your body and do not wear the jewelry until it is completely dry. Other pollutants can tarnish your silver. Be sure to remove your jewelry when cooking, cleaning, swimming, or taking a shower.StorageSterling silver can oxidize quickly, first turning gold and eventually black.
