After spending three days using fabric softener, scrapers, vinegar and water to get wallpaper paste off of the dry wall, a lightbulb went off in my head. I got my bottle of Krudkutter and sprayed it on the glue full strength. Lo and behold, it washed right off with a wet washrag. I could have saved myself two whole days.
You can buy it at Lowe's for $12.99 a gallon. I also clean carpets with it, pre-soak my white lace valances in it (takes all of the gold out from the gas furnace), and just finished cleaning the grout in my tile floor with it. Hope I'm smart enough to think of it first the next time I go to do something

Hi , Does it take grease and smoke residue off walls?
thanks, nanareth Anchorage, AK
How about vinegar and water? Like half and half. Spray it on and let it set a few minutes. Use an old credit card to scrap away any residue left. Cover up wooden base boards, and floors so they don't get soaked. Good luck.

How do you remove wallpaper paste residue once you have already painted over it with a primer?
By Dale from Kirksville, MO
I am afraid you will probably have to sand it smooth, if you've painted over it. I believe the paste residue is the hardest part of going from wallpaper to paint. It took me a full day using TSP, a plastic scraper, a sponge, (and then going back and rinsing it all) to clean my kitchen. Worth the effort, though. My nicely painted walls look good. (12/30/2009)
Well, just how bad is it? If you didn't realize you didn't have it all off until you primed (I know just what you are looking at) sanding it off is the only way I can think of. If it is entire walls, that task can seem impossible.
BUT, if you know how to do any type of ragging, colorwashing, or some other type of paint design you can camouflage it. (01/01/2010)
I would say that sanding is the only way to make it smooth now. Try 120 grit sand paper. (01/07/2010)
How do you get slimy wallpaper paste off a wall before you paint?
Mom from Meridian
I'd first try TSP, that is what you clean a wall with before you paint it anyway, so, you'd be killing two birds with one stone. Also, if you don't want to do that, you might first try white vinegar mixed with water (which you probably already have on hand). You need about 1 part white vinegar to 3 or 4 parts water. If this doesn't work, go to your local Home/Hardware store and they'll have something just for this (but, I'd bet they'll tell you to use TSP too!). (08/24/2006)
I've heard that you can spray white vinegar on old wallpaper paste and it will break it down, and then you can wash it away. Good luck. (08/25/2006)
