Like dirt and grime, rust is not attractive and it can spread if not removed from the surface it has set into. Rust forms when liquid is allowed to stand on a metal surface that is prone to oxidation, such as steel or iron. The liquid eventually eats into the metal surface and deteriorates it as oxidation does its work. A number of expensive commercial chemicals are on the market for removing rust, but the naturally occurring compound borax, a salt of boric acid, can also remove rust from your home's or business' surfaces without the expense or hassle of other chemicals.


Use a borax mixture to remove rust from surfaces including tile.
