I have removed the paper backing of a border (the previous owners just took the top layer off) that is on a painted wall. Now I am left with a sticky glue, the kind that is left behind from sticky labels, not wallpaper paste.
How do I remove the glue without damaging the paint below? I intend to paint the walls, and would like a clean finish without a textured line from the glue. There is about 20-25m to do.
Thanks
Bob
