BISSELL® PET PRO OXY urine eliminator formula works in all our BISSELL® upright carpet cleaners to remove tough pet stains and odors like urine. It discourages pets from going in the same spot again, too. This formula is safe on carpet, upholstery, area rugs and similar soft surfaces. It's also safe for use around kids and pets when it's used as directed. It's formulated with biodegradable detergents and doesn't have any heavy metals, phosphates or dyes, making it earth friendly. In fact, the U.S environmental protection agency carefully evaluated the ingredients in this formula and awarded it the agency's safer choice label, meaning it's safer for the pets and people in your home and better for the environment as a whole. Speaking of pets, 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. We're proud to design products that help make pet messes, odors and pet homelessness disappear.
