Spotless Stainless Rust Remover (Cleaner) and Protector is a revolutionary new product that removes rust and the "free iron" that causes rust from Stainless Steel and enables a rich chromium surface on Stainless Steel which reacts with oxygen in the air to form a tough protective oxide layer. This oxide layer protects Stainless Steel and will extend the time between cleaning. Spotless Stainless does not use caustic chemicals that are dangerous and toxic to the environment.
