The "Paws and Claws" carpet cleaning formula has "met its match" here. Great job! Left the carpets smelling fresh and clean. It removed stains that I honestly did not think would come out. I had this aggravating stain in front of one of the exterior doors to our home. After going over the stain a couple of times with my cleaner with this product, the stain came right out. I'm impressed! Our carpet is older and kind of worn. This made it look really great, overall! I would definitely recommend this product to others!
