How to remove bird dropping stains from painted surface?
Does anyone know a good way to remove bird dropping stains from a painted surface? A car in particular. This stuff is very acidic, and even though I clean it as soon as possible, it still leaves a stain - seems like the acid burns right into the clear coat. I have tried mineral spirits, Fantastik, tire bleach-white, I even got some professional scratch removing cleaning wax, thinking I could buff the clear coat back out - nothing seems to work. Any ideas?
