I have a black foam type of pad under carpeting dating to the 70's. It is a lovely shade of orange! Anyway, the deal with this pad is...when it was installed it was glued around the edges of the rooms but not the entire floor. The wood floors underneath of the carpet are lovely and I don't want to refinish and lose the 100 year old patina-if I can avoid this at all. What I have been able to do is this: I pull up a corner of the carpet and remove as much of this pad as I can but a thin layer remains. I then can rub this off of the floor (with my finger) using a lot of time and patience and there is no residue left behind. So, I am HOPING that there is some sort of treatment I can do to this pad residue to get it off QUICKER! I have a staircase to do as well and the pad was glued to the steps.
ANY ADVICE is welcomed and appreciated!
