I found it more effective to wet the residue down with a spray bottle of wallpaper remover, and then use a razor blade in a holder to gently scrape it off. You will need a light touch and you must hold the blade almost parallel to the wall, but the residue scrapes off very easily when its wet/damp.

Its a slow, tedious job, but not really very hard. Sanding it might also work, but you will probably have a lot of dust.

Oo ohh, this post brought back memories! Our first house had layers and layers of wall paper. A three bedroom with nine foot ceilings. We scraped every wall to remove it all.

As posted above, we found that spraying and using a razor blade with a handle (a scraper?) worked best. We would spray and let sit for a bit then come back. We ended up with quite a system. Oh boy though, every time I see wallpaper in a house we look at I get the shivers. :)

bcarlson, I guess I'll try your method first, is there a wallpaper remover you'd recommend?
Famcook, that sounds exhausting!!! I can see why you'd hate wallpaper.
