My house is over 100 years old. The ceiling in the living room is made of plaster and has a large plaster medallion. There are some areas where water damage has caused the plaster to fall off leaving the lath exposed - I am in the process of restoring the plaster to these areas.
My question is that there is some wallpaper that is glued onto the plaster and I am looking for a solution to remove the wallpaper - I have seen some articles that talk about using hot water to soak the wallpaper - I have also seen some articles that talk about using fabric softener. I am looking for a recommended solution that will work and not adversely affect the plaster.
