WP CHOMP! is fabulous for removing wallpaper. After peeling off the top layer you spray WP CHOMP! on the backing, wait a minute, and then the backing peels right off without any scraping. It can't get any easier than that. I bought the concentrate today because I used most of the spray bottle for the kids' bathroom. I have three more rooms to do and one border. I'm not too stressed about removing it now.
