Old wall paper paste can be removed in much the same way as one removes old wallpaper; just a heavy duty detergent and warm water would work wonders.
In case one has used a wall paper steamer to remove the wall paper it can be used again similarly to remove the paste. After spraying use a broad knife to remove the thick glue splotches; a rough cloth or coarse nylon scrubbing pads may prove to be more useful.
Today a number of chemicals and scouring tools are available that can be used to remove both the wall paper as well as the glue. After the task is over one should wipe the wall with a sponge to remove any traces of the glue, the whole procedure should be done wearing gloves and protective glasses or a mask.
Please keep in mind that glue is a toxic substance and any traces of it should be removed from all tools before using them again and the hands should be washed thoroughly.
