Please Help! I am removing old wallpaper in my bathrooms. No problem. I want to paint the walls, but there is this yukky aqua 'something' that has been literally slopped on the walls under the paper. This stuff is unevenly spread therefore I cannot just prime over it. Nothing seems to take it off other than brute force and many coats of 'Mean Green' ( a spray cleanser). I have spent hours and hours at this. None of the conventional wallpaper removing solutions have fazed it. I am wary about using acetone. HELP!!!
