Roebic K-67 Liquid Drain Cleaner, Pipe Buildup Remover with Bacteria Enzymes for Household Drains and Sink Traps, Safe for Kitchen and Bathroom Sink, 32 fl oz

I had a slow sink drain that constantly got clogged again and again. Now it is draining fast and doesn't ever get clogged anymore. I noticed another review about this not working when using drain cleaner right before this. Don't do that; drain cleaner kills bacteria. If you must use drain cleaner to take out the clog before using this, wait a few days for it to rinse away first. That's what I did.

Toilets and sinks run like charms. No back up and water everywhere. Worse in the shower to if this old house and it's older pipes.

The good news is it finally worked. It really did completely clear a clogged bathtub drain. Our septic is very old we are treating it with Kid Gloves. The bad news is it took twice the amount explained in the instructions and very careful increasing doses in 12 hour periods. When I took off the metal piece that covers the drain in the bath tub I saw it had an ugly gooishy sticky buildup on the underside suggesting that was clogging the pipe. I used a glass measuring cup to pour the directed amount of K67 into the drain and I left the drain hole cover in the measuring cup with a bit of K67 covering it. I was hoping to see the action of the K67 dissolving the material because I couldn't observe the action inside the clogged pipe. The bottom line is that over a week of pouring increasing amounts of K-67 down the drain and leaving it for 12 hours then showering the slow drain did clear and the drain cover I let sit in varying solutions in the measuring cup did come almost clean. So I am satisfied with this product and I plan to use it every so often throughout the year. I think it's a bit over hyped.

Seems to work on some clogs better than others.

My drain was so clogged up that no water could flow through it again. I tried so many products on Amazon, but nothing worked. I gave up, and started camping out in my kitchen with disposable dishes and forks and spoons, because I was afraid to call a plumber, because of COVID. I did not want anyone in my house. A whole month passed, when I saw this product "Roebic Liquid Drain Buildup Remover, Exclusive Bacteria Ends Slow Drains and Prevents Clogs". It seemed so easy to use and safe, I'm 85 yrs old and afraid of Chemicals. So I tried it. I used up the whole bottle and nothing happened. Then I used the plunger in total desperation, I ran water and kept pushing the pluncher. Black dirty water came up for a long time. Then I heard gurgeling noises, and kept pushing the pluncher hopefully. Soon the water started to drain slowly, and I kept pushing the pluncher. The water moved faster and faster, emptying my sink, until the glog was completely gone, and I could wash all my dishes. I feel so exhilarated, that I immediately bought another bottle for maintenance. My glog was like cement in there, and whatever is in this bottle must have eaten through it and loosened it, but without the pluncher's help, I think that I could have never dismanteled it. I usually never report on products, but this time I felt I could help someone who tried everything like me and gave up.

I don’t know if this product works or not because I cannot get the bottle open. No one I know, and I know some very strong people, can get this bottle cap off. I am planning on poking holes in it and draining out the contents, but this is unacceptable to be unable to use a product because you can’t open it

Shipping from AMZN was horrible - paper envelope; 1st bottle somehow broke and the paper envelope disintegrated. As for the product, I think the product is great - have a slow flowing shower. Tried snaking it but nothing clogged. So, tried this for 4 nights. Shower is flowing really well now. Used the remaining liquid on kitchen sink and waste disposers side (no issues) just as precautionary and used up the liquid. Didn't quite get 4 nights out of what's left. But, will buy this product again; maybe not from AMZN. Horrible packaging.

I noticed water draining really slowly in the bathroom sink months ago, but for whatever reason, I didn't do anything until it looks like it was really clogging up a week ago. I decided to try this product because it's safe for the pipe. It didn't do much with the first 2 applications. I came back to this product page to read reviews to see if anyone had shared any tips. Thank you to those who mentioned the use of a plunger! After my 3rd application of this product, which still didn't seem to work much, I took my plunger after pouring a pot full of hot water, and bam! It worked! I started to see a few black speckles floating in the water and the water went down. I was thinking of trying Green Gobbler after using this bottle but I think I will stick to this brand for a while. I will keep using it for maintenance. I'm so happy that the clog is gone!

以前から使用しています。生ごみにそのまま、ほんの少量をふりかけると、殆ど臭いません。 特に、カニの殻や生魚の処理後には絶大な効果です。 猫のトイレにも使用していますが、本当に臭いが気にならないです。 本来の使い方ではないかもしれませんが・・・（笑）

Bei einer leichten Verstopfung hat es nicht geholfen.

Works great. Cleared my kitchen sink drain right away.

台所の流しの下の臭いが気になって、購入してすぐに書いてある通り３日間適正量を試しました。しかし、臭いは相変わらずしています。今晩で４日目、今日も続けてみます。値段的にもしかしたら安いかもと思って買いましたが、全然効果が見られないので、高くつきました。評判の良い商品を買い直そうと思っています。買わなければ良かったと思っています。

Took 4 times to clear my drain. It worked eventually but took too long and having to leave it for 6 hours is a long time before flushing the drain.
