After polishing my car (w/ rotary) I came across some areas that had a small amount of splatter from the SIP that I had used. Probably had been there for a few days drying. Thought I could just spray something on this and wipe away. NOT! Tried: APC 10:1, APC 4:1, Prepsol, IPA/H20. Nothing seemed to work. Ended up claying the car. Aside from the obvious..cleaning up right away, is there anything else that would have dissolved the dried SIP?
