We have used Chem-Dry of Indianapolis a couple of times over the last few years. One reason I chose them is that I used to clean carpets as a part time job, and I really like their process, which does not leave so much moisture in the carpet. Excess moisture is a real problem for carpets, and with Chem-Dry you just avoid all that, and the carpets dry so much faster. On one job they did for me, we had a 12 foot by 40 foot gymnastics tumbling mat that needed to be cleaned. I mean this thing was absolutely filthy. Chewing gum stuck on it, and all kinds of stains. I had even swabbed the backside of it down with bleach, and changed the water three times, and it was still a mess. When Chem-Dry of Indianapolis got through with it, it looked brand new. I mean freaking brand new! Five Stars!
