CLR Calcium, Lime & Rust Remover - 28 Ounce Bottle

This product removes scum and cleansing my shower very well

Love the stuff it does work nicely

Didn’t do the job I was hoping it would glass shower door crude.

Used the product to clean rust and calcium build up on toilet and calcium deposits on sinke/bathroom faucets and showerheads. IT WORKS! I should open a college appartment moveout cleaning service just for this purpose! Used this product for 3 major cleaning projects of college student bathrooms during moveout over the last 3 years in order to help them save a heafty cleaning deposit. These apartments generally do not have soft water SO rust/calcium build up is atrocious. How these kids live with the unsightly MAJOR RUST in the toilets is unfathomnable but guess they are busy getting an education, not worried about the rust/calcium buildup. Once I am finished with the bathroom, IT IS SPOTTLESS and so shiny! Every time I have completed the project, I wish I had before and after pictures. NEXT TIME FOR SURE! DIRECTIONS: Follow them. I use thick vinyl gloves in all cleaning projects. For the really really rusty/calcium build up, I dont dilute the product. Depending on how much build up of rust/calcium there is, you may need to extend the product contact time. Then, scrub using old rags, scrub brush and for those hard to get at places, an old tooth brush. Then rinse or flush. Repeat as needed. A hint: you know the product is working when you start to see it foam on the rust or calcium. THIIS PRODUCT IS AMAZING!.

We applied fertilizer to our yard and some of it blew onto a joining concrete. A day or 2 later, we notice horrible rust stains on the concrete and was devastated. New home, new concrete. Searched the web and found CLR. Bought a 28 oz bottle of CLR to test what it would do. Applied nearly the entire container in an area about 2-3' x 4-5'. Put it on and scrubbed hard with a stiff garage floor broom. The directions said it had to be removed in 2 minutes so that's what I did. I then pressure washed the area and about 50% of the rust was gone. Very disappointed so I gave it another shot. This time I left it on for 3 minutes with hard scrubbing. Then pressure washed it off and I would say 98% or more of the rust is gone. Pressure washing by itself did NOTHING. If I hadn't used my pressure washer above, not sure if I would have had the same results. I have an electric SunJoe pressure washer that I've had for about 5 or more years and it still works great. Lower pressure than most gas units (2000 psi verses 3000 psi). I rate this unit better than the 2 previous gas washers I've had. NO gas to buy, less noise and my gas units just didn't hold up like my SunJoe. Disclaimer, I don't use the SunJoe that much so don't know how it would hold up with more frequent use.

Always use gloves when using. Protect your eyes with protective goggles. Works Well. No Scent. Very easy to use.

I'm not sure if I used this product incorrectly, or if the surface that I applied it to was too rusty, but CLR performed in a way that made me feel that it was simply "OK." I mainly tried to use CLR to clean a rusted soap dish in my bathroom's shower, and at first I diluted the solution, applied with a rag, waited the amount of recommended minutes, and rinsed with cold water. The result mainly consisted of a slightly shiny rusted soap dish, but the rust was still very much there. So I figured I would just put some undiluted CLR in a spray bottle, which the makers of CLR DO NOT recommend, and apply it to the soap dish directly. I applied, waited, rinsed with cold water, and this time some of the rust came off and the soap dish was really shiny. Still though, the rust didn't budge for the most part. Perhaps I did something wrong, but I read over the instructions over and over again only to achieve the same result. I will say that CLR is a lot better at removing calcium and lime, but I do not think it performs as well with rusted objects.

Great price great product easy to use

Productazo! Es caro pero vale la pena en mi caso planeo usarlo cada 6 meses y si se gasta bastante no es muy rendidor pero los resultados fueron muy muy buenos.

In tealta ho preso quel prodotto per smacchiare su barbie vintage macchie verdi (ossidato dalle orecchini in metallo) ma non ho ancora provato. Ma ho provato pulire vetri della doccia, segni di calcare e un ottimo resultato! Spruzzato, aspettato 1-2 min e passato panno e tutto senza nessun segno di calcare! Unica pecca che lascia un odore sgradevole (per me) tipo di curcuma, nauseante e insopportabile che mi dirava in bagno 2 giorni, ma lascio 5 stelle perché fa il suo lavoro

The only thing that helped removing limestone buildup on bathroom tile. It's quite strong and pretty caustic - use goggles and face mask if you intend on working with this for longer than 5 minutes. Vapours are a bit nasty that way. But it worked, when pretty much everything I had tried before - failed. Best effect with some ceramics-grade fine steel wool.

Decided to try CLR in the hope that I could get a Shark 'Liftaway' Steam Mop working. I hadn't used this mop for about 2/3 years prior to trying this. After persevering with my routine, the mop sprung into life. Having flushed the system a number of times with 'Distilled' water, the mop is as good as new. I had tried a number of things prior to using CLR and all failed. Saved a lot of money when you consider the price of a new Shark mop. In my case a great purchase.
