DIF is the way to go for wallpaper removal. It's quick and easy, you need to follow the directions exactly. I peeled off what paper I could, used the paper tiger to score the walls and then sponged on the DIF and warm/hot water mixture. I let it sit for about 10 minutes and reapplied, again letting it sit for 5-10 minutes. With a 3" scraper it just came off!!!! Amazing.
