The 32 OZ. DRAIN TREATMENT AND CLEANER is the simplest way to unclog your drains quickly. I used it in our shower drain, but can be used in other household drains as well. Just follow the water to treatment ratio instructions, pour down the drain, and wait for instructed time. I poured in drain at night then let it work overnight before using the shower the next day.
