I had an issue with the Orange hand cleaner. Whatever that black crud all over the radio and speaker is, the Orange or GoJo would not cut it. In a seam on the lid, I put some orange cleaner and let it sit a while to hopefully dissolve the crud. It started dissolving the paint. So Orange cleaner no more. I tried a few different things and finally Mothers Chrome polish cut the crud easily. But, it would, if used too aggressively, cut through the paint. Then I GoJo’ed it again to get off any residue. Let it dry and waxed it. 

I used fast Orange, no pumice. Never again on any painted surface.
