BIG D® ENZYM D digests organic waste and destroys odors associated with the decay of organic matter. It is highly effective in eliminating the organic salts associated with urine which cause odors. Specially bred enzyme/bacteria cultures attack and break down uric acid molecules by digesting the source, just the way nature does it– but in minutes rather than days or weeks. ENZYM D also contains BIG D® deodorant, which neutralizes odors on contact. Scent: Mint; Physical Form: Liquid; Application: Odor Control; Capacity (Volume): 1 gal.
