I've just given my new car its first wash. After rinsing the paintwork, I went to work on the wheels and then went back to the paintwork to dry it off. There are marks on the paint where the water had been but no residue. You can just see where the water had been. The car had a ceramic coating applied just over a week ago. I wondered what the best way to remove the marks might be; a quick detailer or a water spot remover? The water spot remover seems to apply to marks caused by hard water but the marks don't seem to have been caused by that (although I could be wrong, of course). The water here is not particularly hard. Any advice greatly appreciated.
