Purchased to remove lime rings in toilets. With extraordinary effort to limit the dilution effect of water the toilets were flushed and CLR concentrate was used with a pad and applied liberally. Without flushing the scrubbing and additional application was done three more times on three toilets. All of which were new 3 year ago. The reduction in lime build up on the water line was perhaps 40 - 50% after an hour of continuous application and scrubbing. The result was just fair. Not great as expected. Personally there has to be a better product out there. Otherwise muriatic acid used with great

doesn't work on rust in a sink
i have a porcelain sink with a rust ring around the base as a result of the metal from the stopper piece touching the sink (there should be a rubber part that prevents these two from touching---and has since been repaired). i got this cleaner to try to remove the rust ring. i tried the 50/50 dilution at first with no avail, despite scrubbing away at the rust with a toothbrush after letting the cleaner sit on it for like 15 minutes. i then let the cleaner undiluted sit on the rust for 1 hour and still did not get all of it up with scrubbing. fairly convinced that this cleaner is not doing what

CLR for toilet woes
CLR fixed our toilet!!! We have a 5 year old Toto toilet (worth around $800 CAD) that we inherited when we bought our house two years ago. It started to not flush well about six months ago but we couldnt figure out why. Turns out there was calcium and lime build-up in the front of the toilet at the bottom, where it sends out water with force from the tank, but the build-up was inside the tunnel- thing (sorry, I dont know the name for it!) where the water shoots out and not that evident from just having a look from above. A plumber helped us out virtually and asked us to take a picture and vide

For years, I had a calcium ring, cement color, in the toilette. Brushing it with all kind of products like Comet, using heavy-duty elbow grease and applying man-muscle power didn't do a thing. That pesky stubborn ring would stay for years. I do my own detailing on my cars and could not believe could not win at a toilette challenge. Now, with the covid claustrophobia I went mad [ok... madder] and decided to attack the calcium ring stain. I did my web studies, and had two choices, this product or the Lime-a-Way. Home Depot carried the CLR, they were great and easy to acomodate the purchase, with

Hard Mineral Stains GONE!
I was so disgusted with one of our toilets, no matter what I used in it to clean it, there was this hard build-up in the bottom. The toilet is a newer style and not old enough to be replaced. Cleaning the past week, I decided to see what some CLR would be able to do to it. So I poured, probably 2 cups of CLR into the bowl and closed the lid. About 3 hours later, I went back and flushed the toilet. I can't tell you how happy I was from that flush and the CLR!! There was just a tiny spot left in the bottom, which came right off with the toilet bowl brush!! It is pristine now!

I have used this product for several years. Whenever I encounter calcium build up on plumbing fixtures, this product has always removed these deposits with ease. I recently used the CLR to remove the calcium line on my swimming pool tile. After applying with a garden sprayer, I let it sit for about 5-10 minutes. I then pressure washed the tile and was pleased to see it had removed the mineral deposits. It is much safer to use than acid. Try the product on a small test area before covering a large area. Some deposits are very stubborn and may require more elbow grease with an abrasive pad and a

Not as good as I had expected
I bought the CLR to remove the calcium buildup inside my cordless kettle. I followed the instructions exactly as written and it didn't work. Yes, I had a thick buildup, but I thought multiple applications would do the job. Well, they didn't. By multiple applications I mean I used the whole CLR bottle on the one kettle. Out of frustration, I decided to try a suggestion I found on the internet. I put vinegar inside the kettle and left it overnight. Guess what, next morning there was no calcium left.

CLR vs a Navel Jelly for rust removal/conversion
I used it to remove rust from grills. A automotive rust remover like naval jelly would have been better. Often these have phosphoric acid that converts the rust to a black oxide ( Iron III oxide) and can be rinsed away thus stops/slows corrosion. CLR did work to a degree. It is lactic and gluconic acid and still left rust behind that needed a lot of wire wheel work and sanding. Canadian Tire has Gelled Rust Remover that would have worked better.

TOTALLY ACCURATE DESCRIPTION OF USES
Lives up to the manufacturer's promise. Could not release vanity faucet assembly because of lime/calcium buildup. Soaked item for a fifteen minute period and was amazed at the result. Original brass appeared, mounting hardware softened up and then was able to disassemble. Running the item under warm water restored the faucet assembly's original bright finish, replaced worn valve cartridge, reassembled fixture with no further problem. I cannot understand the difficulty described by others in cleaning a shower head. This product will do the trick, absolutely. It's great, the price is reasonable

Used in shower cubical to remove soap & calcification around shower mixer. Sprayed undiluted form from spray bottle. Let it sit for 3 minutes, then used soft wet sponge soaked in water rub solution off, followed by cold rinse. Works pretty well, everything sparking clean. Use good quality face mask & eye protection, will burn eyes, throat & lungs. Otherwise recommend this product.

Well.... I've used CLR in the past in coffee makers and humidifiers successfully
Well.... I've used CLR in the past in coffee makers and humidifiers successfully. We are now a couple of months into the Covid-19 epidemic. Our church in the Texas Hill Country has wisely decided not to have people meeting on the church campus for the past two months. This is important because we are in an area not yet served by city water. Hence we have a reliable well, and because of the subterranean lime stone we have extremely hard water with a lot of calcium. The toilets in our facilities were not flushed often enough and had a heavy lime building in the bowl. I tried a 50/50 water CLR &

Doesnt work on hard water, limescale or calcium build up. I put this in a bucket for my kitchen sink sprayer and shower heads for 15 mins (didnt dilute it with water). I did this 3 more times and got the same results. This product didnt work. They mustve changed the ingredients or recipe from when it first came out years ago because my grandmother never had an issue with this product but I do.

What else is there?
CLR, for those who just got here is basically an outstanding product. No jokes. Just great. There must be others other there than do about the same thing, but CLR Is the best known and the one I trust most to get the job done, without destroying anything. It could be a bit more powerful IMO, but as-in? I am very happy with it. I am always looking for it to go on sale to get more.

Best thing for limescale, depending on the surface
I've used the product for many years. It's not great, but it's better than just about anything else on limescale. It's not working so great on my fiberglass tub. Short of really strong acid or scrubbing, it's the best. I'll just have to work on it a few times.

worked for my clogged car heater :)
Okay, I know what the instructions tell and that you are not supposed to use it on copper, aluminum, etc. But I was getting tired of my heater not working in our brutal Saskatchewan winter. I flushed the system many times during the last 2 years and tried many different solutions, all in vain. My radiator (heater core) was always clogged and was blowing icy cold air. So I decided to try this CLR stuff. Again, I was aware of all the risks, the last thing I wanted was to do any damage to my heater core. I disconnected the hoses from the heater, drained the antifreeze, then diluted this product w

CLR is the easiest way to clean scale from my evap cooler pads. I turn the fan off, pour about a pint into the water, and let the pump run all night. The next morning I drain all the water, hose out the suds, and my pads are mostly clean again. No muss no fuss. I do it at least once per month.

I read up for best product to clean build up of calcium mineral deposits on our shower tiles. we used the product as directions. did not make much difference. then we were told white vinegar, baking soda and #00 fine wire wool. %75 cheaper than a bottle of CLR and did did an amazing job.

Something has Changed - and not for the better!
I have used CLR for at least a decade, and while it has never worked all that well on rust, it no longer works at all, and it barely works on lime. Bought a second bottle thinking that the one I had was just a fluke. Sadly, the new one was equally ineffective. If anybody knows a product that works, would appreciate that info.

Ring in your toilet??
We all have that pesky ring in our toilets that appears due to the water in Arizona. No matter if I clean my toilets on a daily basis, this ring appears faintly. A friend of mine suggested this afternoon became tired of using up pumice stones. I allowed it to soak for about five minutes and POOF, the ring was completely gone! No scrubbing until you're at the end of your pumice stone and the ring takes much longer to show up again. I'm sold!

Cleaned a nasty toilet like new. AMAZING!
I've used this stuff before with moderate to good results. But this time I had the ultimate challenge. We have hard water in the Midwest. That means a brownish calcium builds up in fixtures (toilets, sinks, tubs) unless they are regularly scrubbed -- and even then they can build a very hard, crusty deposit. A utility room toilet was neglected for years until the threat of company forced our action. I shut off the water valve, then used a screwdriver to chip away at the large chunks for an hour. I gave up and got the CLR. The standing bowl water was mostly scooped out, and I started brushing on

It's CLR, works great. I'm a commercial electrician and work close to the beach. A lot of my tools end up rusted due to all the salt and moisture in the air. I take them and soak them in CLR, a gentle scrubbing with a wire brush and they are sparkling clean. I then spray some WD-40 on them and they are good to go for the next round.

Not for steel or iron type rust
Bought it to remove a rust stain on concrete caused by rusty steel, only to find it doesn't work whatsoever. To be fair the product label does not claim to remove these type of rust stains. It claims to remove surface rust stains caused by hard water buildup which is not what most people would call rust.

Doesnt do a single thing
Bought this to get limescale off of my shower floor, and some surface rust off of metal utensils due to hard water. It does nothing. This product is probably more likely to add more rust and limescale to your things. Do not waste your money

Great product for when regular cleansers will not do.
I use CLR for many applications. It is great for cleaning things that regular cleanser can't clean. Been using it for years. Great on lime and calcium stains. I have yet to use it on rust.

Average at best
I used this on my stainless steel dish drying rack in the kitchen. I followed the instructions and even did it a second time. It didn't magically lift the rust off in all areas. I ended up having to use a metal brush on it to get the stubborn rust off. I was rather disappointed with the results seeing as I had to do an hour of hard scrubbing to get it clean. Disappointing.

I used this product to eliminate calcium ring around toilet bowl. Works great. Just make sure to shut off water supply to toilet and flush to lower water level. Apply product and scrub with non- metal brush several times.

Great for removing limescale and rust. Excellent for cleaning electric kettles. Just pour it in. swirl for a few minutes. But is expensive. White vinegar gets same results but is slower and needs to be heated

Old House Chrome Bath fittings
I have an old house that needed its bath tub and wash basin valve stems repaired. The hot wash basin faucet was leaking thru the top of the bell housing. Over time, lime and soap residue had accumulated and was not removable with scraping. I put the faucet and the bell housing in a bath of CLR and immediately noticed residue floating to the top. After soaking for about 3 hours, the chrome looked as good shiny and bright. Also, our handheld shower nozzle will clog from the mineral deposits. After soaking in CLR, the deposits will loosen and and the residue can be brushed away easily. Sorry I di

Good but not great
Even though it is supposed to be septic tank friendly it isnt so friendly to skin. Maybe it does have some warning on the bottle, but like most humans we tend to open and use. The product took 3 hours of soaking fully immersed in the CLR to remove calcium deposits. Wasnt aware it would take so long. The advertisements make it look like presto its clean.

Rust Removal On Concrete Garage. Floor
I had lots of rust spots on my garage floor from a leaky car radiator. Tried CLR to remove it first by following directions to mix it half and half with water. Noting much happened. Then poured it on the stains full strength. let it bubble for a few minutes then rubbed with steel wool. Took it off completely.

This stuff is great, I soaked a shower mat in a light mixture, I wanted to see if it made any differance to the mat. I left it for about 1 hr before I removed it, I couldn't believe it, it was crystal clear and sparkled better than new. This stuff is great I use it on all kinds of cleaning jobs.

Keep your sinks, tubs and toilets clean and free of calcium buildup
I use CLR to maintain the sinks, bathtubs, shower enclosure and toilets. There is very hard water where I live. Even had a water softener installed but still get some buildup.

Be very careful where you use this
I've used Evaporust for years with never a single problem. Decided to give CLR a try on some car parts this past week. I thought of CLR because the parts are part of the cooling system of the car- specifically the thermostat housing and there are lots of mineral deposits. I put them in the CLR, checked them after a few minutes and saw the minerals were starting to dissolve. Left it overnight to finish and checked them first thing in the morning. Sadly the main body of the part was aluminum and buried in the fine print of the label after "marble and granite" in the "don't use with:" section is

Bought this as recommended for cleaning washing machines. I followed the instructions as indicated on the directions: run with CLR and run again with just water. The smell of the washing machine is much, much better; though, there' still lingering smell. I'm guessing this is due to years of use of the washing machine without cleaning it. Caution: do not follow with colored wash - as I did. I noticed that my colored-clothes have white spots, though very, very light - as if it was bleached out - but nothing major. Will regularly use monthly and see how it goes.

It saved replacing our shower faucets. The plunger on our bathtub faucet was hard to pull up actvaing our shower. I used CLR to disolve the calcium on the faucet and the plunger came loose. Everything works super smooth now
October 9, 2020
Still the best. I usually transfer this into a large spray bottle to make it more economical. Works wonders on my kettle, countertops, sinks, faucets, shower tiles etc. Tried other cheaper brands over the years but kept coming back to CLR for a good reason. In my opinion it's better to shell out the extra $2 and get a quality product that does what it says it would.

Once upon a time 50 years ago, I worked at a hardware store. We recommended CLR to our customers for lime, soap scum removal. I have purchased many modern magic remedies, that have frustrated my attempts to remove the fog from our glass shower walls, so in desperation I went back to my old favourite. Now I need to find uses for the closet full of cleaners that dont quite measure up!
February 18, 2021
I use this to clean the scale that builds up in my Ninja coffee bar and in my electric stainless steel tea kettle. It works extremely well, just don't use too much when you run it through the coffee maker (use about 1/2 up to 1 ounce of CLR per 10 cups of water)because it will foam up and come out of there vent on top. If you have an electric tea kettle I advise not to run it through while it's on, instead dilute a little CLR with some hot water and let sit in the bottom of the tea kettle powered off, then rinse well.

Slow flushing toilet
Used CLR to help with a slow flushing toilet. Cleaned out the little return holes along the rim with an alum wrench. Then drained toilet. After draining poured the CLR into the overflow tube in the tank and watched until it also filled main fill hole at bottom. Let it set for 15 minutes then turned water back on and flushed. Toilet is working properly. This is a 30 year old toilet and I love that it holds 3 gallons of water. I have a 40' run to the street so not comfortable with 1.1 gallons of water to do the job. Plus the toilet looks brand new.

I hope they keep making this it works great on soap build up in showers and tubes glass shower doors. Sparkles like new.. I used many years ago and worked great so I just found it again at walmart . The trick on showers make sure surface is dry use glove wipe on or spray let set 20 min. Get dry cloth soak solution on cloth wipe over what you have sprayed se the miracle the best stuff I have ever used..

Does great for calcium and lime but the rust part needs work.
We bought this because all of our pipes are galvanized and copper. The house was built in 1968 or 1969 and as far as I know, all but a few of the pipes under the sinks are original so we have had tons of issues with calcium and lime build up. We've also noticed lots of rust. I opted to get this because the commercials are so catchy. I even went around for a week telling my guy to CLR it as we were working on the pipes. Overall it did a great job with the calcium and lime deposits. I soaked all of our faucet handles and spigots. I even soaked the shower head. We flushed the pipes with this and

Talk about an amazing cleaner that can tackle some of the hardest jobs I have ever had to clean. The CLR cleaner is great at handling calcium, lime and rust that has built up and accumulated anywhere inside or outside your home. I have used it several times and purchased it again after my first bottle. I have renewed our old shower heads that had build up on the sprayer portion causing it to be less powerful than when we bought it. I took the shower head off the pipe and soaked it in the CLR for about two hours while I did some other cleaning. When I came back the thing looked like new, I did

Makes my life a lot easier when I have to clean our old bathtub which grabs everything and gets dirty easily....I used to spray the tub with a tub cleaner, put powder Comet, liquid clorox and kneel in front of tub to scrub for a long time....then I discovered this CLR and that is the only thing I use with a sponge, wet the tub, wet my sponge with CLR, pass it on the tub (not even pressing hard), rinse with water. And my tub looks brand new! I clean all the tiles and faucets with it too! Life is easier when cleaning with this! Highly recommended!
