CLR Calcium, Lime & Rust Remover - 28 Ounce Bottle

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.

This product removes scum and cleansing my shower very well

Ok

Great price great product easy to use

Love the stuff it does work nicely

I used Vinegar to soak my coffee machines and other small appliances such as hot water pot urn to get rid of those hard water deposits. It takes an overnight soaking to get a clean result. I tried CLR based on reviews with a little skepticism of those reviews. Wow, CLR blew my mind. It works like magic and clean my hot water pot in exactly 2 mins. I did not dilute CLR as instruction since I didn't think it would work so I tried it at max strength. Fill 1/6 full in the water pot, then slowly row the pot to let CLR reaching other area. After two mins, my pot is clean like new. I was so excited and immediately pour the used CLR into my coffee machine and this time I took a picture before cleaning. After two mins soaking, CLR did its magic again as you can see in the 'after' picture. So no more vinegar soaking for overnight. Although it is more expensive than Vinegar, but I don't need large volume to soap the whole pot or appliance. And the result comes back fast.

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.

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

Wow it really works! My taps are like new had to use it twice on it, also it removed the rust on one of our tiles, will definitely keep using this, does the job.

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.

CLR is the best! When it foams, you know it's working. No scrubbing needed for limescale, rust, and more. Wish this came in the foaming spray bottle version, but I'm so happy to have the power of CLR in my house.
