I picked up a used receiver hitch that has areas of rust scale underneath peeling paint. I want to clean it up so it looks decent and prevents rust from developing further.

What would be a good method to remove the rust so I can repaint it? Wire wheel on an angle grinder? Flap disk? Something else?

I don't have access to a media blaster, nor is the piece valuable enough to pay someone to do this.

After removing the rust manually, is there a chemical worth putting on it to take care of any rust I missed and help prevent rust in the future; something that is OK to primer and paint over?

Any recommended brands or type of rattle can primer/paint to use on the receiver hitch?

Sorry if these questions have been answered before, my searches didn't pull up what I was looking for.

Thanks for your help.
