Look for loose paper near the corners of the room or under the faceplates for switches and electrical outlets. Use a thin, metal putty knife to work under the paper and lift it from the wall. For difficult to remove wallpaper, use a scoring tool to cut through the paper to allow the water to penetrate.
Use a sponge to apply hot water to any remaining wallpaper. Be careful not to saturate the drywall. Allow the water to stand a few minutes to dissolve the glue, then work with a scraper to remove as much of the backing as possible. A gel wallpaper remover is useful for removing any remaining paper.
Once you remove all the backing, work to dissolve the glue, and rinse it from the wall. Use sponges and hot water for the task. Once the wall is dry, sand any irregularities you discover, and fill them with an appropriate drywall filler.
