The most common way to stop rust on metals is by fragmenting or brushing the metal surface using sandpaper. Another rust removal method is to apply phosphoric acid which converts the red iron oxide into black ferric phosphate on direct application to rusted iron.
Most people know WD-40 Multi-Use Product as a lubricant, but it was originally used as an anti-corrosive by the aerospace industry to prevent spacecraft from rusting. WD-40 can help remove rust from metals like iron, chrome, and stainless steel without further damaging the surface of the metal or removing the paint.
