Zymex 2 battles stubborn contaminants Kimball Midwest's Zymex 2 Enzyme Cleaner and Odor Eradicator utilizes special enzyme bacterial culture to attack and break down uric acid molecules and organic contaminants. The nonpathogenic, non-acidic, non-caustic formula deodorizes instantly as it is sprayed where odor originates. It attacks grease, fats, proteins, organic waste and uric acid by digestion. After digesting the contaminants, the bacteria no longer function and will not leave residue.
