Rust occurs when oxygen comes in contact with metal in the presence of water. This results in oxidation, or rust. Rust weakens metal and makes it look unattractive. Rust is often inevitable, especially on older pieces of metal. Light rust can be removed and stopped at home, without any professional help. Once rust becomes too heavy, it is often best to completely remove and replace the oxidized metal. Since light rust can become heavy, it is important to stop it from spreading.
Wash the metal. Remove all traces of grease and dust. The type of cleaner you use will depend on the type of metal you are cleaning. If you are cleaning a car, for example, use car wash soap and water. Allow the metal to dry completely.
Use a wire brush or sandpaper to prepare the surface. Brush or sand away any rust on the surface. Put on the gloves and protective eyewear.
Apply the primer with rust inhibitor over the affected area. The easiest way to apply primer is to use a spray primer. Cover the entire area. If the metal has never been painted, prime the entire area.
Wait for primer to dry completely.
