I CRIED CUZ IT WORKED!
IT WORKED! Year before the pandemic, we've been dealing with a slow drain in our old home. We dont have plumber money so we've been putting up with the drain and using a plunger and/or plumr. This year its gotten so bad. Plumr was not working. Plunging stopped working eons ago (I shouldnt be surprised, ignoring small issues turns to big ones) So I've been trying so many brands and so many of their different items. Drano, Green Gobbler, other Plumr types of drain clog liquid. They all werent cutting it. Then in comes CLR. Directions say to use 2oz everyday overnight or when not in use for 7 days. Unfortunately I kept forgetting since tub always had water slowly draining in it or was being used. So i was only able to use it on weekends this month. This week though, the tub completely stopped draining. These past 3 days I've been forgoing a shower and doing the best I could. I was dying for a shower today. About 1/5 of the CLR was all I had, so I poured all of it in the clogged tub and prayed. It did work a lil, after an hour. Just in time for fam member to get ready for work. But drain was still slow. I come back to check for my turn after fam left for work and the drain was back to not draining at all. I later check a second time and see tub is still filled at same level. I broke. Insert frustration, crying inbetween trying to snake and plunger the drain for over an hour. Nothing, still the same amount of water. So I stop to go calm down for another hour and think of game plan to scoop out the water. As I'm about to go get a scoop, I hear a slow light gurgle increase to the most wonderful sound I havent heard in years. THE FAST GLUG GLUG OF DRAINING WATER IN THE BATHROOM TUB. I cried again watching the water quickly drain. Then turned on the faucet at full blast to rinse out the CLR and watched gloriously as the water disappered as quickly as it came out of the faucet. BUY THIS MIRACLE LIQUID. FOLLOW THE DIRECTIONS. AND DONT PROLONG THE DIRECTIONS LIKE I DID. Thank you CLR. I will buy more of this as preventative maintance now for my tub and all other drains in my home.

Works
Works a little too well I think. A week after using it and had to call someone to clear out the sewer line to the street. I suppose it was inevitable though.

Be patient!
I read some of the other reviews and I don't think people understand what this stuff does. It is NOT a drain cleaner per se, no 15 minutes and all clear. It breaks down organic material -- hair, soap, toothpaste over a period of a few days. I poured it in at bedtime since it needs to sit untouched for about 8 hours. It took about 4 days, but it was all clear and my bathroom sink drains like a charm. So remember, it's not a 15 minute wonder like Drano or anything, it takes time. I use it periodically for a couple of days to keep the drain clear and put a mesh strainer over the drain so the hair doesn't clog it up in the first place!

Works slowly
I put the whole bottle down my laundry overflow pipe, then left it over night then flushed it with hot water and then waited a day and went and got zaps drain opener then I used two bottles of zeps, so I’d say it would take days of drain unclogged to unclog the laundry overflow pipe, and I also put some toilet bowl cleaner in all my toilets. So I have no clue what helped but it worked after 5 days of drain treatment between CLR and ZePs

It does what it says it's supposed to do
I've used this product for quite some time and I find that it does exactly what they tell you it's supposed to do as long as you follow directions you will get excellent results if you don't follow directions then I guess you won't get the desired results that you are expecting which then again that now becomes your fault for not following directions but I find that this is a great product and it's reasonably priced and I will continue to buy it because I've been buying it now for quite some time possibly even years now at this point I use it to clean my cups to get the tea stains out I use it to clean my pot that I heat up my water because of the calcium buildup I've used it in my humidifier that is a small room humidifier to get rid of all the calcium buildup because of the hard water situation causes all that calcium buildup inside it's really a great product and I believe that if you just give it a try and you follow the directions you will see that it works like it says it's supposed to work I have a lot of faith in this product and I will keep buying it

Small than picture and don’t work it’s making worse. Horrible
I am still waiting after two days that I have put that product in my shower, and it’s still like those pictures. My shower now is worsen than before I tried to fixing with this horrible product. All my body is itching because my bathroom is inside my bedroom. I don’t know what kind of toxins are in the product. Please don’t waste your money!!! Better go to Walmart and buy draine

Great item literally saved the day
We had an almost city wide backup during a recent "almost flood" around here. As far as we could tell my lines blocked by something from sity lines, thought it was mine so did usual cleared all house lines basically anything from mine got stopped on whatever the block was and mine went from that Telltale gurgling in the tub when you flush the toilet to all but a dead stop. So much so that it blew off the cover on out flow pipe in basement. After many attempts at clearing it with every trick I know I did some research and ended up buying the CLR which was a good thing cuz we had gotten them almost clear and they blocked again. After fixing the outflow pipe we poured this straight into it says it'll go out 50 ft well my 50 foot auger couldn't quite reach the clog so it definitely does what it says it will. By the next morning my lines were running 100% clear and have been since. Not so much as a gurgle so this is one I will be buying again. Since we knew the clog was over the 50 Foot Mark even if it was barely I had search for something that would hopefully be able to reach it and CLR did the trick considering the multitude of previous attempts and the fact that it was they'll put in and then rinse for nose supposed to be in overnight it was if he still but by the next morning like I said 100% clear literally Save the Day and my sanity cuz I wasn't sure how much more of this I can take.

Used for Preventive Maintenance
Like the active bacteria consuming the grease build up in the drainage.
