There are many different ways to remove wallpaper. You can use a steam cleaner, a solvent like fingernail polish remover, or you can try to scrape it off. If you have a lot of wallpaper to remove, it might be worth your time to invest in a commercial wallpaper removal product. These products usually contain methylene chloride, which is a powerful solvent that can quickly remove wallpaper. However, methylene chloride is also toxic and dangerous, so be sure to read the label carefully before using it. There are also some less hazardous alternatives available, such as citrus-based solvents or vinegar solutions.

Vinegar is a mild acid that helps break down the adhesive that holds the wallpaper in place. Hot water helps to loosen the paper and make it easier to remove. To make the wallpaper remover, mix 1 cup of vinegar with 1 cup of hot water. Pour the mixture into a spray bottle, and spray it on the wallpaper. Let it sit for a few minutes, then start peeling off the wallpaper. Be sure to wipe down the walls with a wet cloth afterwards to remove any leftover adhesive.
