Need some help defeating rust

[Rodimus_Prime]

I pulled off a bunch of bolts in the front bumper support that have some surface rust on them, im also pulling off a bunch of the brackets that have rust on them as well

I want to strip all of them of the rust and repaint them to the original color

Is there some type of liquid I have to buy to do this, or whats a good way to get rid of the rust, some of the bigger stuff obviously I can sand or run a dremel over but im not sure what to do with the bolts

Soak them in oxalic acid overnight. Its a chemical used to bleach wood. after you soak them, use a white scotchbrite pad and the rust will come right off. It will not harm the coating already on the metal, whether its painted or plated.

There is a product called Safest rusr remover that works great and is non toxic.
