Saltwater and chlorine can damage the metal. ✓ Remove your jewelry before you go to the gym. There are a lot of natural chemicals in sweat. ✓ Avoid direct contact with products such as perfume, sunscreen, hairspray, and lotions. Harsh chemicals may cause damage. ✓ Prevent sleeping in your jewelry. Close contact with your body's chemical make-up can create build up on the metal. ✓ Always keep your gold fill jewelry in a dry place. The dryer you store it, the longer the sheen will last! Gold filled jewelry is still not completely solid gold so if not properly taken care of the gold layer can eventually wear/scratch off over time.
