I've been using P&G Chem-Dry for twenty some years. They are excellent and I recommend them often. They do a really good job. I don't like steam cleaning because it takes so long to dry. I have my carpets cleaned by P&G Chem-Dry every two years and Scotchgarded as well. This helps the spots come right up. In all the times I've had them, if there's ever a problem, they come right back out and don't charge me. Once time I had a spill from a leaking Costco package right after a cleaning, and they didn't charge me to come back out. P&G Chem-Dry does a great job. They are on-time and they are nice people. In my world, when I buy something, and it works, I just stick with it. Only one time did they charge me a minimum fee for spot removal in between cleanings. Five stars for P&G Chem-Dry.
