This works great on my carpets. I have used it for over 6 months now. Good cleaning, not overpowering in smell, and easy to use. I pretreated with this, rubbed it in, then let it soak for a bit. Cleaned with my Bissell machine and stains are gone. It seems to deter my pet from trying to use the same spit again to "Mark". Thank you Bissell. #Sweepstakes
