  • Patent number: 10982425
    Abstract: A system for capturing and destroying hair and waste within a shower drain includes a basket placed in the drain which holds a rod including an enzyme blend. The basket captures hair or waste that is washed down shower drains. The enzyme blend neutralizes the hair or waste. The result is a clear drain and clear plumbing, with minimal manual labor. The basket does not require removal because the hair and waste are neutralized before a clog can develop. The enzyme blend is safer for both users and the plumbing systems treated than conventional drain cleaning chemicals.
