Gosh, Jabber, I haven't had to worry about wallpaper in a while. We use the All Natural cleaner from Seventh Generation for general cleaning. But I don't know if it will work on wallpaper. I know it took the dirty, greasy marks off the wall from where our dog used to park himself. We also use it to clean the dog door. This stuff is amazing, spray on the area and wipe off with a dry cloth. It might take two applications for really bad spots, but we use it because it's non-toxic and environmentally safe. There's also an enzyme cleaner we use for rugs called Bac-Out by a company called BioKleen. Seventh Generation has all kinds of non-toxic cleaners that we use - all of them work well.
