How 2 get rust off of a bolt?

To remove rust from a bolt, start by soaking it in a solution of vinegar or a commercial rust remover for several hours to loosen the rust. After soaking, use a wire brush or steel wool to scrub the rust away. For persistent rust, you can also try using a penetrating oil like WD-40 before scrubbing. Once clean, rinse and dry the bolt thoroughly to prevent future rusting.
