BISSELL® Pet Stain & Odor formula works with all BISSELL® upright carpet cleaners to remove tough pet messes and tough pet odors. It also works to remove smells left from stains like cat urine. This formula is safe to use on carpet, 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. In fact, the ingredients in this carpet shampoo have been carefully evaluated by the U.S Environmental Protection Agency 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 BISSELL Pet Foundation® and its mission to help save homeless pets. When you buy a BISSELL® product, you helps save pets, too. We're proud to design products that help make pet messes, odors, and pet homelessness disappear.
