What is the best way to remove the residue from outdoor carpeting. I have ripped up the carpet, and scraped off the backing that was still attached to the concrete.<br />There is still some residue on the concrete from the backing, along with the adhesive.<br /><br />My plan right now is to use a wire wheel on a grinder to mechanically remove as much of the adhesive as possible. I was able to remove a good amount of it using a little elbow grease and a hand wire brush.<br /><br />Does this sound like a good plan, or does anyone know an easier method? I don't really want to use chemicals as this is an outdoor patio, and there is landscaping in close proximity.
