“Rust is the term we use to describe red iron oxides produced when ferrous metals corrode. Rust is the common name for the chemicals that result when iron reacts with oxygen and water.” “The chemical reaction that causes rust is called oxidation. The oxidation process eats away at the metal and creates visible rust on the metal's surface.” Rust is typically on metal, steel, or iron.
