Answers:    I own a 21/2 year old son who like to tear my wall article off, I can rent him to ya, LOL No really here is a product called DIFF. you can return with it at any hardware store, it's in windex shaped bottle, and it's neutral blue, but it is a gel, it is a product made to take sour wall paper, try that! Good Luck
