It always amazes me that the workers get out every stain, even the ones that I consider a “lost cause”. We chose light beige carpet when we moved into our house. That was before we had any pets. Over the 10 yrs., we’ve accumulated a dog and *5* kitties. Chem-Dry has gotten out everything that these animals could throw at it, including when we had an 80 lb. old greyhound (now deceased) who brought a considerable portion of the yard in on his feet every time he came in. I would not hesitate to recommend Chem-Dry to anyone, for any kind of cleaning problem!
