Climb a ladder to reach the strippable wallpaper border.
Loosen the edge of the strippable wallpaper border using a knife.
Peel the wallpaper border away from the wall at a 10- to 15-degree angle. Avoid peeling it straight across as this may cause damage to your walls.
Mix one part fabric softener to two parts water in a spray bottle. Spray the solution on the paper backing or adhesive that remains on the wall after the border is removed. Allow the fabric softener solution to sit for a couple of minutes.
Scrape away the adhesive and any backing paper using your scraper. Since the fabric softener breaks up the adhesive, this should be fairly easy to do. Reapply the fabric softener solution on stubborn areas.
Wash away any remaining wallpaper border adhesive and the fabric softener solution using a clean sponge dipped in warm water. Rinse the sponge often and wring it out as you move onto another section of the wall.
