How do you remove self adhesive posters that are stuck to the wall?
I would try steaming them. >
Try using dishwasher liquid diluted in hot water. Score (make lines
with a sharp knife just through the top layer)the paper, then
thoroughly wet the area and let sit. It should be able to be peeled
off after a few minutes. There are other ways to do this, but this
always worked for wall paper, so thought it might work in this
