We have tried so many carpet cleaning solutions we were ready to pull the carpet up and go with linoleum. However, In my experience the Furry Fresh product has done the best job we have ever experienced. Two weeks later and the carpet still smells fresh, only a few stains have reappeared (I didn't pre-treat them as well as the others), but even those residual stains are faint and my wife cannot see them. I will buy again. Thanks.
