We had some wallpaper borders to take down and avoided doing it, for years, due to the fact that we didn’t want to spend all day scraping. Then a friend told us about Dif and it’s awesome.
You just spray on some Dif, wait 15 minutes and the wallpaper border pealed right off. It doesn’t get much easier than that.
You can get some Dif on Amazon or check your local hardware store. We found our s at Home Depot and are very glad we did.
