Start with a tool called a tiger paw, which fits in the palm of your hand.
Simply roll it over the face of the wallpaper, perforating hundreds of small holes all over the surface.
Next, mix a good wallpaper remover solution (available at any hardware store) with water. Sponge it over the wall allowing the perforated holes to absorb the water.
Once the water gets behind the seams of the paper and starts weakening the glue (generally it’s a water-based wheat paste), the wallpaper should be fairly easy to remove.
You’ll probably find this to be a simpler method than the old-fashioned steam-removal systems.
