Enzymes are created by bacteria to digest the proteins found in urine. These bacteria (sometimes called "bugs") are living organisms that essentially "eat" uric acid crystals. The affected area must have the right conditions so that the bacteria can work: it must be humid, not too hot and it must not contain chemicals that can kill the bacteria on contact. Hydrogen peroxide breaks down proteins and microorganisms found in urine through oxidation to quickly treat odors for the short and long term. Our formula also includes surfactants and an acidic pH that effectively removes urine stains.
