- ALL JEWELRY should be taken off before showering/swimming/exercising, and kept clean & dry in a closed storage when not in use. Jewelry should be properly cleaned once in awhile in order for it to last longer.
BRASS naturally oxidizes depending on the air & body chemistry but brightens up quickly if you rub with lemon + water then rinse. Polishing with a soft nail buffer also works. It is not irreversibly tarnished, just temporarily oxidized.
GOLD FILLED to clean use mild dishwashing liquid & water or jewelry cleaner. Be careful not to tangle chain, gold filled components can last years of regular wear.
