|Mold feeds on body oils, shower products, cooking oils and bacon grease that collect in the corners of your shower and kitchen. That’s why we created Cleanz™, the first ever active enzyme caulk that eliminates mold food! By taking away the food, we literally strip mold of its power to grow. Plus, unlike mildewcides and repellents that wear out over time, our active enzymes are permanent for long-lasting results. Active enzymes stop mold before it has a chance to grow. won’t pill away from bathtub (or any other surface), maintains watertight seal. Resilient surface withstands scrubbable and chemical cleansers. Smooth application, quick water sleanup and no offensive smells.
