The best way to remove rust from a metal object is to use a combination of chemical and abrasive methods. First, you should clean the surface with an appropriate cleaner or degreaser to remove any dirt and oil that may be causing the rust. Then, you can use an acid-based rust remover specifically designed for the type of metal you are working on. Finally, once the rust has been removed, you can apply an abrasive material such as sandpaper or steel wool to further refine the surface.
