WD40 staining?
Anyone ever had staining on side of coach? Sprayed awning brackets last night. Just got back from road and noticed spots. Tried to rub off with water with no success.

Been using it for over 40 years on boats, aircraft, and RV's, and never had it stain a solid surface. I use it on the campers to remove tar and road grease from the front. So far it hasn't hurt either the aluminum or the fiberglass.
