Trying to remove wallpaper can be difficult and if you are using the wallpaper remover from the local discount store it can get expensive. Try using liquid fabric softner mixed half and half with water. Just put it in a spray bottle and spray walls. Let it soak in a bit and then start scraping or peeling the paper off. You can even use the "cheap" stuff to make your mix.
Try it out!
Have a great day!
