Sani Sticks keep your drain pipes clear and odor free, all year long! Sani Sticks as seen on TV are super concentrated cleaning and sanitation sticks that you drop in the drain once a month to prevent backups, clogs and nasty odors. The stick rests in the pipe-trap and slowly releases a blend of enzymes that break down food, grease, hair particles and other organic materials. Keeps drains clear, water flowing and pipes odor free. Just one stick per drain per month. Sani Sticks are biodegradable, all-natural and non-toxic. Safe for use in all drains. Septic safe. Includes 24 Sani Sticks.
