I use this on a monthly basis to keep our drains from clogging. I cannot give an honest opinion if your drain is clogged but it keeps ours free thus far.

Better to buy this product to have on hand if you have occasional drain problems. It works great and it’s cheaper to buy this way rather than a single bottle. It won’t go bad.

Folks, this drain cleaner does exactly what it is supposed to do - clear clogged drains! To be honest, the two major brands (Drano and Liquid Plumber) are both very fine products that work as advertised.. I buy both brands, depending on what Sam's has available, to get a much better price from a warehouse club than paying double the price per ounce at my local grocery store..

Takes care of most drain clogs. Very good price!

My family and I LOVE this item!

This was recommended by my plumber to put one cap full in my bathroom sink and tub once a month to prevent buildup in the pipes from hair etc. works very well and no mor clogs

Very great product clears drains fast good price

this product works phenomenally, but I wish there was a clear strip on the side so you can see how much product you are using/how much is remaining. instructions tell you to use 1/5th of the bottle, but how are you supposed to know when you're pouring when to stop?

Does what it claims. My wife and daughter seem to leave hair everywhere.. and down every drain. Totally did the trick.

High hopes but zero results in three bathroom sink drains. Treated the drains multiple times with the Drano but it made zero difference. Flushed out the Drano and used a toilet plunger to clear the blockage. Problem solved. The sinks drain fine now.
