Yellow residue on bathroom walls.

We think that when they did a faux plastering on the walls they did not take down the old wallpaper and the sticky residue is wallpaper glue. You re not imagining things. These rooms are often damp and full of the residue of shampoo soap and dirt which are foods for a lot of bacteria and single cell organisms that form yellow mold.
