    Why does mold grow so quickly? Because you’re feeding it! 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!

    You can use Cleanz® all around your house, including:

    • Countertops
    • Backsplashes
    • Kitchen fixtures
    • Bathroom fixtures
    • Bathtubs
    • Showers
    • Sinks

    It adheres to most building materials, including:


    • Aluminum • Nickel • Steel
