Biocide Systems is proud to introduce their Bio-Shocker line of Chlorine Dioxide odor eliminating products. These products exclusively use the revolutionary ClO2-DMG Technology that delivers the super odor eliminating power of Chlorine Dioxide, also known as ClO2. Whether you are dealing with cigarette, pet, vomit, urine, rotten food, mold, mildew, fish, skunk odor, and any other odor type you can think of, this line of products will get rid of the foul odor permanently. The secret lies in the fact that the ClO2 is a gas that can penetrate deeper and more effectively than other non-gas products.
