There are a lot of different ways to get wallpaper off and a variety of products you can use. But what you're essentially trying to do is to deactivate the adhesive that holds the paper backing onto the wall.
  1. Remove the face plates on the walls you'll be working with, and cover the outlets with electric tape to protect them from liquids. Also put a drop cloth down to protect the carpet or floors.
  2. If you're lucky, some paper may already be loose, and you can just start peeling. Otherwise, consider using a gadget known as the Paper Tiger. It's a roller, on the underside of which are little teeth that will perforate the wallpaper .That allows any solvent you use to get behind the paper and dissolve the adhesive more readily.
  1. Apply the gel or other commercial solvent with a paintbrush, and give it some time to soak in and loosen the wallpaper (the label should specify how long).
Working smarter: A less expensive solvent option is warm water mixed with a few tablespoons of vinegar in a spray bottle.
  1. After the solvent has a chance to soak in, start working at removal at a seam or edge of a perforation, scraping with a Paper Scraper, plastic spatula, plastic putty knife or drywall knife.
  2. Keep applying the solvent and scraping until all the wallpaper is gone.
