It is the alloy that oxidizes and causes the black silver sulfide (Ag2S)/tarnish to form on the silver. Two products commonly used to remove it are Twinkle Cream and Wright’s Silver Cream. Even though this can be labor intensive, the beauty of polished silver flatware gleaming in elegance on a formal dinning room table provides a truly artistic dining experience.
