I purchased the DIF Gel Wallpaper remover. I would not recommend it to anyone. I have been 2 days trying to remove just a boarder from my sons room that has only been on there for 2 1/2 years. Our house is only 2 1/2 years old. This is the worse remover. I am now using vinegar and hot water and it is working great. Just thought someone might want to save some money and use what they may already have in their home.
