BISSELL Pet Stain & Odor formula works with all BISSELL upright carpet cleaners to remove tough pet messes and odors. It also works to remove smells left from stains like cat urine. This formula is safe for carpets, area rugs, upholstery, and similar soft surfaces. It's also safe to use around kids and pets when you use it as directed. Plus, it contains biodegradable detergents without any heavy metals, phosphates, or dyes, meaning it's earth-friendly. The U.S. Environmental Protection Agency has carefully evaluated the ingredients in this carpet shampoo to earn the agency's Safer Choice label, meaning it's safer for the people and pets in your home and better for the environment as a whole. Speaking of pets, Bissell proudly supports the Bissell Pet Foundation and its mission to help save homeless pets. When you buy a Bissell product, you help save pets, too. We're proud to design products that help make pet messes, odors, and pet homelessness disappear.
