Could someone please explain to me the origin, or origins, of the faint "swirly scratches" that almost all cars seem to have? I know you know those pesky things I'm talking about!! I used to think they came from "brushed" commercial car washes, however, when I went to the DC auto show with some other forum members, I pointed out and they agreed that roughly 8 out of 10 of the showroom quality, A-game, brand spanking new, shiny as the sun cars on display had these faint swirly scratches. They're something I've never understood!! Why do even brand new cars have them? And is it possible to get rid of them and how?
