If you've been living with your old wallpaper because you thought it was just too difficult to get off, well, wait no longer. Here's a four step process that will get it off in a flash.
Start by using a wallpaper perforating tool like this to create hundreds of small holes in the old paper.
Step two. Put a gallon and a half of hot water in a garden sprayer and add to it, an enzyme-based wallpaper stripper like this one right here.
Step three. Spray on the wallpaper stripper starting at the top of the wall. Now you want to thoroughly saturate the old paper. You may have to make two or three applications. Now you may have to give this 20 or 30 minutes for those enzymes to work.
And step four, just peel it off. Now the key to this method is to be patient. Give the stripper time to do its work. You shouldn't have to do any scraping. If there's any residual paste, you can wash that off with some more stripper in a sponge.
