How to unclog your drain


Slowly pour 1/5 of the bottle (2 cups) down the drain. For the really rough clogs, use the entire bottle.


Let it sit for 15 minutes, or in the case of standing water, until the drain is clear. Liquid-Plumr® Full Clog Destroyer™ won't harm pipes if left overnight.


Now that your clog is dissolved, flush away any leftover gel with hot water. It's that easy.

For garbage disposals, follow the same usage directions and flush with the disposal running. Avoid all splashing.

  • “Clean Pipes”

    I regularly use Liquid-Plumr to keep my pipes flowing freely. When I do my cleaning I pour half a cup down the drains in my kitchen and bathroom and I never get clogs. The plumbing in Chicago is old and needs the help of Liquid-Plumr!

Know Your Pipes


Keep out of reach of children. Harmful if swallowed. Avoid splashing. Injures eyes, skin and mucous membranes on contact. Do not use with ammonia, toilet bowl cleaners or non–Liquid-Plumr® clog removers, as splashing or the release of hazardous gases may occur. Clean up any spillage immediately.

  • What should be done if my problem gets worse after using this product?

    This may happen when a partially dissolved clog gets lodged further down the pipe. We recommend trying another dose of this product. However, if the problem continues to persist, you should call a plumber as there are some plumbing situations that even Liquid-Plumr cannot fix.

  • How long should I wait before flushing the drain with water?

    Wait at least 15 minutes after pouring this product down the drain before flushing with water. If you have an especially difficult clog, you can safely let the product sit overnight.

  • How much of this product should I use per occasion?

    For best results, we recommend using 1/2 of our 32-ounce bottle or 1/5 of our 80-ounce bottle for every clog problem.

  • Can I use this product in a drain that contains standing water?

    Yes. This product is designed to pour through standing water. It is formulated to clear the full clogs that cause water to stop draining.

  • Can I use this product to keep my drain from clogging?

    Yes. This product is very effective on full clogs and slow flow drains, and with regular monthly use can help keep your pipes flowing freely.

  • Is it safe to mix Liquid-Plumr® products with any other product?

    No. Do not use Liquid-Plumr® products with ammonia, toilet bowl cleaners or other non–Liquid-Plumr® clog removers, as splashing or the release of hazardous gases may occur. We do not recommend using Liquid-Plumr® products with non–Liquid-Plumr® products. It is safe to use any Liquid-Plumr® product in the same drain.

Rated 5 out of 5 by from This is the best liquid plumber clog destroyer because Ive used it on an old place where there was hair in a bunch of other stuff stuck in the drain and I put it in there and left it in there for about 15 minutes. I came back and poured hot hot water into the drain and it went down so smoothly. I recommend this to anyone who has clogged toilets or clog drains because it will get the job done.

Rated 5 out of 5 by from Clogged drain because of hair? This stuff will unclog it! Im a girl and have tons of hair so its no wonder that after so time the drain gets clogged. Believe me I try to start on it but. It hard sometimes. Thankfully this stuff fixes the problem by eating away the hairs caught in the drain.

Rated 5 out of 5 by from I use this every month or 2 months when the sink doesnt drain. It is sometimes effective in the first go, but generally in the second try. It is not very affordable since you have to use a large amount for it to be effective. I will buy it again.

Rated 5 out of 5 by from Long curly hair, PCOS and hypothyroidism don't play nice with drains. Liquid plumber has helped when even cleaning the drains constantly after showers stopped working (YUCK!). Afyer 20 minutes problem solved. I always keep some in the house. Make sure to keep it stored safely and when using the area must be well ventilated.

Rated 5 out of 5 by from Worked Great!!! First time I ever used this. I woke up on my day off with my boyfriend telling me the bathroom sink is clogged. I took the P trap out to make sure nothing was clogged there. I have a small snake but I couldn’t break up the clog, i plugged several times nothing would come loose. I thought I would have call a plumber. So I ran to the store to pick up drain cleaner, I figured for $4 I had nothing to lose. Poured it in set a timer for 15 minutes and flushed it with hot water. I couldn’t believe it cleared it right up. My friend was here and I kept saying I can’t believe how fast and great it worked. Thank you so much you saved me money and waiting around forever for a plumber to show up.

Rated 5 out of 5 by from Quick & Easy We have a bathroom sink drain that has an aversion to anything except water. LOL This stuff is like a magic potion. It works quick and is easy to use. After the first use, we now use as maintenance, a little once a week. Just to keep things flowing smoothly.
