Rugs, Carpets and Carpeting - remove commercial carpet glue off concrete?

What is the best and quickest way to remove commercial grade carpet glue from a concrete floor? It has been down 12 years.
We have removed the carpet and some padding and some glue are resisting removal.

A 4" razor floor scraper and a pack of blades. Dampening the floor to moisten the adhesive, helps too. Don't soak it though!

There are chemical removers too. But you better be sure all the chemical is wasted and rinsed off GOOD if you plan on gluing something else down to the concrete.

This is to advise that the above information is incorrect. PEEL AWAY 5 and PEEL AWAY 7 which are the same produuct with one being a paste and one a gel are used to remove latex and acrylic coatings from porous surfaces like concrete, brick, stucco, etc where the coating penetrates into the surface. After using PEEL AWAY 5 to remove the adhesive from the concrete floor and a power wash will completely clean the surface and make it ready to accept any new coating.

Ya, power wash the interior of your home! Make double sure it soaks all the flooring in the house too, for best results! The sheetrock must be soaked and ruined to know your doing it right. You must have mold growth later to make sure you got it all.

Any recommendations on a scraper? I bought one at Home Depot that has a telescoping pole, but they seem to be perpetually out of blades for it. I haven't started this part of the project yet, so I can still easily replace it.

And no, I don't want to use chemicals... I'm willing to put in the sweat equity to do it right, and I don't want to have to air out my basement in a Georgia summer. Or deal with potentially trashing my newly painted walls.

Look in the phone book under carpet or flooring supplies. There should be a distributor that will sell you the blades direct. Also while you are there get the smaller 4" scraper, to get the small stuff that big stand-up model doesn't get. It's a leverage thing. You have more leverage, with knee pads on, and the smaller 4" scraper, while your over the top of the scraper. I scrap in cresents around me in one swoop after another. It keeps from jambing your wrists, also getting forearm splints from the shock.
