Need a quick eco-friendly solution to removing old wallpaper?
Try your basic garden variety VINEGAR diluted with WATER.
Hooray, how easy is that! I used a wallpaper scoring tool. Be careful not to press to hard if scoring on drywall surfaces. Then I sprayed my water and vinegar solution about 1/3 vinegar to 2/3 warm water. Let it soak and scrape off with a little elbow grease and a scraper.
