Abstract
A tarnish remover/metal polish formulation comprising water, an acid, and metal iodide, such as potassium iodide, is described. The components of the formulation chemically react with the tarnish or stain on a metal surface, removing the tarnish or stain while leaving the metal unaffected. The tarnish remover/metal polish can be applied as a dip-rinse or as a polish. The composition is easily applied and easily removed.
