To remove rust from metal surfaces, rub off the loose rust with a wire brush. Washing the surface with turpentine will remove all grease, oil and dirt from the surface. You can use any of the rust cleaning solutions available in the market and apply on the rust affected surface. In case the surface is heavily affected with rust, the application has to be repeated twice or even more. Remove all the paint with the help of a paint stripper or in case the surface is painted earlier. Now apply rust removing solution and let it dry. The surface can be repainted with two coats of paint.
