Bio-Active Enzymes microscopically remove the cause of the odors at the source. 100% FRAGRANCE FREE ZEOLITE: A very unique mineral that was formed from the glass component of volcanic ash millions of years ago. It reduces the production of unpleasant odors by absorbing gases such as ammonia. SODIUM BICARBONATE: Commonly known as baking soda. It is a natural deodorizer and most importantly, it is environmentally safe to use. BIO-ENZYME SYSTEMS: When added to organic waste, enzymes immediately go to work breaking down the waste and converting it to Carbon Dioxide and Water.
