If you need to remove some wallpaper, mix up a solution of 1 gallon warm water, 2 tablespoons liquid dish soap, 4 tablespoons vinegar and enough wallpaper paste to make the solution slightly sticky. Apply this solution to the wallpaper and let it sit for five minutes. Do *not* let it dry, if it is drying quickly, apply more solution to keep it wet. After five minutes, you should be able to easily peel off the wallpaper using a scraper.
