A good helper/tech that doesn't mind working on their knees and charge accordingly.
Score it, heat it and have your helper attack it and get the bulk of it off with a good solvent and repeat.
No easy way...always seems to be a m'fer no mater what is tried. Older the worse.
Better to have hired help on their knees with their face in the carpet than you.
Maybe check out the "Gun and Cuff" method.
Here in lies the problem.......a good helper that can put some "muscle" into treating and spotting the gum after it is heated up by the wand. My wife, whom is also my assisitant/helper, can't really kneel down because of bad knees, and when she does, I have to stop and help her up. So I just throw her on the wand, and I get down and peel up the gum.
The BEST gum remover was 1,1,1 triclorethane (? spelling?), which just isn't available any more....besides being extremely toxic.
I swear.....gum is a lot more sticky-er than it was 20 years ago.
