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

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.

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.

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.

Product was missing the seal, but not returnable. I used it in the drain, and repeated treatments as directed until the entire bottle was gone. It had no effect on the drain. I bought another bottle of the same stuff at a local store, and the drain was flowing nicely after just one treatment. The bottle I received from this site was just blue water. Skull and crossbones here... you have been warned.

Works but price is twice what you'd pay elsewhere.

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!

I had a slow drain that I couldn't snake. I didn't want to use drano or liquid plumber, so I figured I'd give this a try.I wasn't expecting a minty toothpaste-y mouthwash smell, but I guess since you need to leave it in the drain 6 hours at minimum that's not a bad thing.Following the directions, I used it three nights in a row in our bathroom sink. It made no noticeable difference. I tried it and extra night, no difference.Then, I put vinegar and baking soda down there, and black stuff came up a little and the drain was a little less bad. So, I did it again, and there was another improvement.Stick with vinegar and baking soda and save your money.

A couple of my sink drains had a small odor coming back after you turn on the water for a little bit. I bought this cleaner to help clean the pea trap without actually needing to remove it and clean it myself. After the recommended few uses, I no longer smell that odor anymore.But to make things even better. We recently clogged our kitchen sink. The clog was beyond the clean out valve on the outside of the house. I ran a small snake down the clean out drain, which helped a little, but the sink would still back up. I poured 4 oz of this cleaner down the drain and let it sit over night. The next morning I ran hot water for about 3 minutes and the drain never backed up.
