I have heard from previous, similar posts that vinegar water works, too, but I am glad to say i have never tackled that project.

Any cheap fabric softener will do, best thing I've heard to work, and the cheapest.

I like a product called "Chomp" Works very well and doesn't destroy the drywall. Waterbased product

Having tried several of the above methods to strip layers of wallpaper in our 5400 sf/160 yr-old house, I highly recommend using a Wagner 705 power steamer. You should be able to find a good used model on eBay for under $50 including s/h, & can always sell it when you're finished. The 'paper tiger' is the tool referred to above, but you won't need one with the steamer--unless the paper has been painted & won't allow the steam to penetrate.
