Tarnished Silver Silver tarnshes very fast. You have to spend a lot of time an efforts on cleaning your table and other silver items.

Tarnishing of silver occurs when the outer layer of silver reacts with sulphur. A special coating would eliminate (or reduce) contact of silver with sulphur and thus prevent silver from tarnishing (or reduce tarnishing).
