This was my second time using COIT. Like the first time, I'm extremely happy with my carpet cleaning. However, this time I also asked for my shower tile to be cleaned. It's an old building, so there are a lot of hard water and rust stains. I've tried every product on the market, but could never find anything that worked. The technician told me it would be an extra $150.00 to do the shower and that I may not be satisfied. I figured it had to be better than it was, so I agreed. He was right. The shower didn't look much better, but I wasn't filled with false hope. I would definitely use COIT again, but only for carpet cleaning. I would never ask them to do my tile or grout.
