That all depends on the "grit" of the steel wool, the lubricant used, and the loose nut behind the wheel.J3FF said:Steel whool might scratch the chrome. I know I was scrubbing my chrome with a wheel scrubber and noticed tiny scratches where I did it. So I use a sponge now. I'll have to try this product. Has anyone used steam on their wheels?

I don't think I'd suggest RB-17 (or Hoppes) for chrome; IIRC, it will attack the copper substrate used in the plating process, thereby damaging the chrome chemically...
