Short answer: soap suds.
DO NOT USE Ammonia, toothpaste, nor any kind of Polish nor Abrasive brush.
Protect the E-Coat and your purchase will last & last.
*Reminder - Put on your jewelry AFTER using hairspray, lotions or perfumes, etc.
More: Our plated jewelry has a clear E-Coat which adds longevity, durability and luster to their surfaces. Soap suds from handwashing are best to recharge your jewelry piece's original luster even if the e-coating wears away over time. *Protect the plate - your last layer of defense, because when its gone the brass is exposed which tarnishes. It's a layering game.
