Mix equal parts fabric softener and hot water in a spray bottle. This method works best by focusing on small areas and slowly working across the entire wall. Saturate the wallpapers with the fabric softener spray and let it soak for a few minutes. Use a putty knife to peel the wallpapers away from the wall.

In some cases, and this is only possible to judge after removing the wallpapers to see what is underneath all layers, a plaster will be the best option, specially if there are too many rough and uneven areas.

When fabric softener is applied to walls, it helps break down the glue that's used to stick the wallpapers to the wall. This makes the wallpapers come off much more easily than it usually would and creates more time to be spent in decoration.
