Fabric softener can be a great quick hack to help remove wallpaper in a pinch, especially if you do not have a steamer or there are multiple layers. Apply undiluted fabric softener to the wallpaper with a cloth and allow it to soak. The detergent will start to break down the glue on the reverse of the paper, allowing the paper to slide off of the wall more easily than trying to scrape it with a dry scraper.
