Simple Solution Extreme Carpet Shampoo is formulated to deep clean carpets, rugs, drapes, and upholstery with patented odor-neutralizing technology. Wipe out organic dog and cat urine stains permanently, removing the smell once and for all, rather than masking it. This concentrated formula makes 6.5 gallons, and is safe to use around children and pets when used as directed.
