Very effective, but expensive.
Would RecommendI've used zep for my bathroom sink a few times now. I shave and my kid drops a ton of toothpaste in the basin that tends to clog the sink drain. Zep has always been effective in removal of the clogs. I generally use half the content for about 10 mins before I flush the drain with water. I've had to use the complete can once when the clog was especially tough, but it did the job.

Found ZEP for Bathroom Sinks at Lowe's!
Would RecommendSeveral months ago, I was looking for a product to unplug my bathroom sink. I didn't have a plumber handy so hoped to find something that would work. I went into the Lowe's plumbing aisle and found ZEP for Bathroom Sinks! Hoping it would work, I bought a bottle, took it home & was amazed at how quickly the sink opened up after I followed the simple directions! Now I keep one or two bottles on hand.

Straight to the best
Would RecommendThe only product I’ve found that clears EVERYTHING, and lasts for a good long while, even in 60yo pipes. Works fast, and I’ve never seen and damage as a result of using it. Gets down in the pipes quick, cleans everything up, even way down deep. What more could you need?

bogus product
Would Not RecommendI used as directed , product did not work the least bit. Zep discontinued its guarantee a year ago, that will tell you something.
