Fill a spray bottle 1/3 full with fabric softener. It doesn't have to be exactly 1/3 full, so use your best judgment.
Fill the bottle the rest of the way with hot water. The water should be hot to the touch, but not boiling.
Shake the bottle for 30 seconds to mix the ingredients together.
Spray the mixture on the wall paper. Start in a top corner and saturate 3 square feet of wallpaper. Let the liquid soak in for two minutes.
Grasp the corner of the wallpaper and peel it away from the wall.
Repeat the process, working on one sheet of wallpaper at a time in 3-square-foot sections.
