Re: leave stains
Castrol SuperClean!!!!! I love this stuff. Has very bad water line on outside of my boat, rubbing compound would not take it off. SuperClean and a tire brush, took it right off, and restored the color to the paint, by removing all the oxidized paint. Wish I had a before and after pic to show you how good this stuff is. BEWARE, if you leave it on too long with out rinsing it off, it WILL eat up your paint.
