I'm removing wallpaper right now. Removing the paper itself was easy. The problem now is there is a ton of glue left over.
I'm removing the glue using water+vinegar and then scraping it off. Most of it comes off easily, however there are a few spots where it's stubborn and refuses to come off. There's not much there at all, it looks like a faint stain.
Is it okay to leave little bits like that? I plan on applying a skim coat of mud to the drywall next.
