Just finished removing wall paper in February. It took some time and a little aggravation. Tried the paper tiger found it worthless. I ended up peeling the top vinyl like layer off then using M1 from home depot but DIF is the same did not use the gel. Let it soak in for 5 minutes then peeled it off in whole sheets. The left over pieces and excess paste I used a kitchen sponge (rough side) and M1 remover. It wasn't as bad as I feared but took 8 hours to do a small bathroom. Like someone before me said try it before you pay someone to do it.
