Chem Dry uses carbonated water to clean carpets, so there is no harmful chemical residue left to harm you, your kids, or your pets. They use extraction cleaning, so very little water is left and it dries quickly. Also, since they use little water there is less of a chance for mold to develop in your carpet padding. Go to their web site to find out more and find a location near you: http://www.chemdry.com/.
They don't use subcontractors and their manager actually did my carpets himself. He did a great job and got out everything except for an old coffee stain. The other stains came right out and everything smells fresh and clean. The technician was friendly and on time. They also didn't count my small hallway as an area, so saved me some money too!
