The most effective way to remove rust from metal is by using a combination of sandpaper, steel wool, and a rust-removal chemical. Start with coarse grit sandpaper, then move up to medium grit, and finally finish off with fine grit. Once you have removed all traces of rust, use steel wool to scrub away any remaining residue. Finally, apply a rust-removing chemical to ensure that no new rust appears.
