My ride has a bunch of rusted screws and bolts around the outside body. I'm replacing all of them with new but there are still rust stains around left behind. I tried to use a sponge with the green scubber side to see if that would work (without scratching the paint). Nah. I tried that rust remover chemical that they use to dip parts into. Nope. Any ideas? Something to place on a rag and scrub (in circles)? I haven't tried rubbing compound yet, but won't that scuff up the remaining paint?
