WD-40 works quickly to polish and protect fine silver plates, platters and even silverware. The oil compounds in WD-40 break up grime, leaving a thin layer of protection against tarnish.

WD-40's proprietary mix of mineral-spirit solvents, liquid petroleum and mineral oils displace water and seal out oxygen to restore and protect metal and non-metal items throughout the house. Dirty buildup is easily dissolved and released from the surface with the wipe of a cloth.
There are two choices of application of WD-40. By inserting the included red straw into the spray nozzle, the stream is easily directed to a small area. Spraying to cover larger silver platters and plates is done by holding the nozzle six inches away from the surface and "dusting" in a fluid, side-to-side motion.
WD-40 is not a food-safe solvent . It should be used only to restore and protect silver plates and platters that are not intended for immediate food use. Many fine silver plates and platters are displayed and never actually used for food service. These pieces of display silver are perfect candidates for a light dusting of WD-40.
Rust and tarnish that develop on the surface of silver plates and platters is preventable by sealing out moisture. By polishing silver platters with WD-40, a layer of protection is added to the surface to displace all harmful moisture.
The protective layer of WD-40 on silver plates and platters must be removed before eating from them. WD-40 can be washed off with grease-cutting dish soap.
