Green GobblerEnzyme Drain Cleaner | Controls Foul Odors & Breaks Down Grease, Paper, Fat & Oil in Sewer Lines, Septic Tanks & Grease Traps | 1 Gallon

Works well! Got rid of drain gnats (little black flies) and helped with the drain odor in laundry-tubs and floor drains! Use overnight and let it rest in drain when not using any water and let it work! A cup or two in each drain did the trick, with a couple of applications.

Cleared drain immediately love how easy it was . The storage is enough for a few uses function is awesome. Going to buy more most definitely its awesome product for a bad drainage home. Water retention is right on spot thank you will be buy more green goblin products. Just bought monthly up keep packs . Such a good product for my use

Plumber reccomended enzyme drain cleaner after an emergency call out. Seems to keep kitchen sinks drains clear, but does not work on girlfriend's shower hairballs.

A poorly designed kitchen make this a necessity for me. An eight foot drain pipe with almost no pitch to it, clogs quite easily. I use this every two weeks, and the drain runs well. I usually run a bit of hot water at night, give it time to drain out of the pipe and then dump in a quart of this. I believe the warmth accelerates the process. In the morning, I flush it out with hot water.

The product itself is worth 5 stars but it is a little pricy. I haven't tried similar products in a lower price range to see if they are just as effective as this product. After a lot research and a recommendation from a trusted exterminator I purchased this to help with a drain fly issue. It has helped with the issue but it hasn't totally eradicated it. I've used it as directed and as my exterminator has directed. It just gets very pricy over time to continue using this product.

This stuff is incredible! Works really well and eliminated gunk related odor and drain flies. Would definitely recommend and buy again.

I bought this product because it's marketed as using natural enzymes to clean and maintain pipes, which I liked in theory. The reason I titled my review “Gobble Gobble Scrum and Rum” is because—while it does work—it only works if your pipes are already fairly clean.If you’ve already got a build-up or smell, this won’t magically fix it. It’s not going to "eat the grease" or clear out years of gunk anytime soon. Realistically, if your drains are already slow or smelly, you’ll need a professional plumber first. Then, maybe use this as a maintenance product after that.Bottom line: Don’t expect miracles. It’s a slow helper, not a heavy-duty fix. Just facts.

I have used this product prior to this order, and it does provide some relief from clogged drains and it seems to keep the kitchen and bathroom drains flowing well. I use it monthly, one cup in the kitchen drain and 1/2 cup in the bathroom drains. There is an "industrial" odor to the product, but it's not too awfully bad, and it's gone when after warm water is used flush the drain. It does keep my drains flowing nicely.
