The best way to remove rust from a metal surface is to use a combination of sandpaper and rust-removing chemicals. Sand the area with coarse grit paper, then apply a rust-removing chemical or paste to the rusted area. Let it sit for about an hour before wiping away any excess residue. Finally, finish off by using finer grits of sandpaper until you have achieved the desired smoothness.
