A steamer is the best way to go, especially if you have a vinyl covering. Just start in one corner, steam and pull up the paper while you keep steaming where the wall and paper meet and pull gently. To remove the paper backing, I used hot tap water in a deck sprayer. Saturate the paper, wait five minutes and use your scraping tool. Don't bother with DIF gel or liquid, even with a Paper Tiger I got terrible results!!!
