Can you use isopropyl alcohol to clean surface before painting?
Isopropyl alcohol also works well for removing caked on compound and polish residue. Isopropyl alcohol should be diluted between 10 and 15% before being applied to painted surfaces. It is not recommended for freshly applied paint to use isopropyl alcohol as it can cause the paint to dry out and crack.
