Liquid-Plumr Foaming Drain Clog Remover, Unscented, 42 fl oz

It's a one shot deal... you use the entire bottle at once, but it did clear a 20 year old shower drain that had quit draining nearly 100%. Standing water. I had to try something! You can't get a plumber to come out and clear one for $8.00. I bought two bottles and only needed one. Cheaper brands didn't work well at all. Just follow the directions.

Works great--although after letting it sit in the sink for an hour, it takes time to get hot water right away. So use heated water from the microwave while you run the water in the sink.

I've used alot of drain cleaners over the years, and this one is the best. I have a bathroom sink in my apt. that tends to run slow if I don't keep up with maintenance. Some products don't do the job, this one cleared the drain completely. I was impressed. I let the foam sit for an hour, then poured 2 pots of hot water down the drain, and the sink drained quickly after the 2nd pot of hot water. The drainage has been clear ever since. This is the only brand, with pro strength foam, that I will use from now on.

Liquid Plumr Foaming Gel is the product to use when one FIRST senses the pipes are clogging. I use it as recommended and my bathroom sink clears out to allow easy flow of water without buildup of water in the sink bowl.

With toothpaste, mouthwash, shaver trimmings slowly slowing the flow of the drain, I use this about once a month. You can really see the difference in drain flow.

Th product works very well but each time I ordered it the lid was loose. On arrival . No other merchandise was affected but this is not a product that I want on my skin.

Didn't work for me. Not sure why but the stars are based off my experience.

seems to work fine but it foams BEFORE it gets down the drain so the sink has a bunch of wasted foaming agent. It did seem to help with a slow drain.

One bottle was leaking before it was packaged. (It was placed in plastic bag. Other one was not)

I followed the instructions with this product but it barely improved the slow flow of a sink. The product that has worked best for me in the past is the one with the snake.
