It will clear your drain
I have four bathroom vanities, one kitchen sink (open drian and garbage disposal sides) as well as a utility sink. In addition to multiple shower drains, a soaker tub drain and a jetted garden tub drain. It's easy to see that with all of these drains, something will eventually need your attention. Sink drains provide relatively easy access to the trap and with a modest amount of effort they can be cleaned out manually. If however the clogg goes far beyond the trap the repair gets a little more intense. Of course shower and tub drains typically don't have easy access to their drain plumbing. This is the answer for these scenarios. Not only will it open up the drains, it will do so quickly and as an added benefit it will help to keep things downstream from clogging in the first place. I have also found that it works well in laundry drains where soap scum and fabric softener buildup can become problematic. It can be used preventatively in utility drains such as HVAC A Coil condensate drains. Who wants to find their AC system shutting down because the condensate tray is backing up? Or worse yet, find out that the system didn't shut down but instead overflowed onto your carpet, hardwood or even worse, into your ceiling if the unit is upstairs or attic located. This stuff works well for opening clogged drains quickly and preventing clogs when used as a maintenance aid. I typically by this in either the large container or in two packs as I want to have it on hand when needed. I also restock quickly when low.

AMAZING PRODUCT!! WELL WORTH THE PRICE!!
I was amazed how this product worked on my slow moving bathtub/shower drain! I had tried snaking it, plunging it, liquid drain cleaner...nothing helped until this. I watched the videos people posted and thought what the heck, I'll give it a try. Ran hot water for a minute, waited 10 minutes, poured 1/4 cup directly into the drain, added more hot water, saw 1 bubble (burp) waited, repeat ran hot water 1 minute, 10 minutes later added the beads, little more hot water...finally drain opened up completely. Will use as a monthly maintenance to keep functioning.

Worked so well I'm ordering it again!
Cleared the drain when no other drain cleaner I tried would, including expensive professional drain clers. This saved me frk having to rent a plumber's snake!

High purity, perfect for soap making
This pure sodium hydroxide is exactly what I needed for making soap. The beads dissolve quickly and consistently. 99% purity ensures reliable results every time. The container is well-sealed and includes proper safety warnings. Works great for drain cleaning too when used properly. Much better quality than what you find in stores. Excellent product for soap making enthusiasts!

Works pretty well with boiling water and plunging afterwards
I didn't get the benefit of hearing a "whoosh" or anything so incredible when I used this on my bathroom sink drain, which is about a century old, which has been getting backfilled with stagnant water when I leave the sink on for more than 5 seconds. After first trying a drum auger I found with no luck, I decided lye might be the solution and used it as part of a trifecta of clog removal solutions. The clog was very obviously deep in my wall instead of being immediately accessible and I'm just a typical 30-year-old with no knowledge of plumbing really... For me, there was no explosion or craziness, but I did don a mask and a full-length coat just in case something crazy did happen (and you should as well if you buy this). After the first pass through with the lye, I didn't notice any change, so I decided to do it again, this time mixing it in a plastic container with the hot water in advance and then pouring it down the drain all together (Do not do this unless you have the gloves and the protective glasses!) and letting it sit for a few hours. When I poured hot water into the sink after letting the lye sit for about 6 hours, it immediately backfilled and I was really bummed out, but I decided to actually *boil* some hot water and pass that through the pipes. A lot of people say not to do this if your sink has a PVC pipe in it but I passed about 10 quarts total of boiling water and started seeing a bit of an improvement at that point. I finished everything up by allowing the sink to fill some and using a plunger on the drain. At this point, all sorts of disgusting black stuff was coming up... but the sink finally returned to a somewhat functional state. I'm sure this clog pre-dated me living in my house and unclogging it felt like a serious effort. In retrospect, I would have probably just paid for a plumber to come out because it ended up eating my entire Sunday. On the other hand, I would recommend the lye as a PREVENTATIVE maintenance tool for stubborn and clog-prone sinks. Personally, I think the plunger technique was the most effective, but this lye definitely jumpstarted the process. I'm guessing if you don't live in a super old house, this stuff will do the job much more easily... in which case, you should buy this instead of Drano because it's way cheaper, but you should also try not to be a Darwin Award winner and maintain a healthy fear of lye, because the stuff is really dangerous to play around with if you're not taking all the precautions.

My Lye Experience Fibbed..
Hmmmm. After seeing the ratings and reviews of this product, and having periodic visits from thr plumber over the years, I thought there might be a chance for a normal draining sink. Like many others have stated, a large sticker was on each bottle that partially covered the directions on a very caustic product. Why not just place it elsewhere? While the directions are specific that you wear goggles and gloves when handling this product, after reading some reviews here, before pouring the lye down the drain, I wear glasses anyway, and stood away from the sink as I poured the lye down the drain. Before pouring the lye down the drain, directions say to specifically let hot water warm the pipes. I simply ran very hot water from the tap. Some reviwers here boiled water on the stove prior to pouring it down the drain. Directions on the bottle simply read to run hot water down the drain until the lye is dissolved. I'm lazy, and didn't boil the water, and anal enough to follow the directions on the bottle to the letter. My results are mixed, mainly because I had a huge mess after pouring lye down the kitchen sink on the disposal side. There is a very pronounced leak now, and as of this writing, I'm still not certain where it's coming from. My pipes seem fine, so I suspect its from the disposal. I will edit this review when I have this repaired. While I never was injured while using this product, do have gloves handy in case of a leak, as was my case. I was very careful and cautious when cleaning up my sizable mess, and escaped unharmed. I ordered 3 bottles. I used all of the lye on two bathroom sinks and the kitchen sink. After I warmed the pipes by running hot water down the drain, I simply began pouring the lye down the drain, standing at arms length. It will bubble and spew water to a degree, so do stand back. The lye did some good, but I'm not "wowed" by spectacular results. Mine were simply okay. Of course your situation may, or may not be the same. I followed directions to the letter, but I only had some noticeable success with one bathroom sink. The other drains remain somewhat sluggish. I knew it was working, especially in the kitchen drain, but in the end, my problem remains. Not a bad product, but not the miracle cure many have had here. With my experience, I would simply say "try it" It might work for you.
