Clorox® Urine Remover for Stains and Odors quickly breaks down urine to eliminate odor instead of masking it. The Clorox Urine Remover formula uses hydrogen peroxide to remove uric acid crystals and break down the cell structure of bacteria, which removes the lingering smell of urine evidence over time. This versatile Clorox urine cleaner is safe to use on most hard and soft surfaces. It is specially formulated for tough-to-clean porous surfaces.
