BISSELL PET Stain & Odor + Antibacterial Formula works in all BISSELL upright carpet cleaners with an Easy Fill System to control odor-causing bacteria on carpet and upholstery. We engineered this powerful formula to remove tough pet stains and be safe to use around kids and pets when used as directed. And this formula doesnt just clean up after pets, it helps save them, too! BISSELL proudly supports BISSELL Pet Foundation and its mission to help save homeless pets. When you buy a BISSELL product, you help save pets, too. Were proud to design products that help make pet messes, odors and pet homelessness disappear.
