CLR PRO Calcium, Lime and Rust Remover, 1 Gallon Bottle (Pack of 2)

I use this product for rust and lime remover. Works like it should for hard water,

CLR is such a useful cleaner. I have a 90 year old home & the kitchen sink is porcelain. It's look so grungy & is so hard to clean... until I started using CLR. Turns out the "dirt" was calcium deposits. So I have squirt bottles of CLR under every sink & spray it on the sinks as a final cleaning stage every week. The sinks look brand new now! Ever get coffee stains inside coffee cups that you can't get off? Here's how to easily clean them off. First spray dilute bleach inside the cup & let it sit 5 minutes. Rinse & see if the stains are gone. If not, spray CLR on it & wait 5 minutes, then rub a soapy brush around the inside & viola, stains are gone.

Years of toilet trouble: slow drain or no flush. Got to point only fluid would go down. Tried everything and a plumber said calcium and lime; brown stain that looked like toilet wasn't glazed. Plumber said leave it in over night but we didn't want to do that and did it for two hours 2x. Amazing !!! This stuff saved us hundreds of dollars.

Used it on mineral deposits in toliet that would not come off. Poured it in the toilet and left it over night. Next day all the stain came off with some scrubing.

I have hard water and this helps. Plumber recommended a calcium remover for my toilets and I chose this product from good reviews. It works very well! I recommend and I’ll continue to buy.

great product for removing stains

Game changer..,Wonderfully made and high quality at an affordable price cost

We have well water that tastes great, but has a lot of lime/calcuim. CLR works great to dissolve calcium build up from plumbing fixtures and rust or calcium build up in the toilet bowl. For toilets, we just dump a cup or two into the bowl, pouring it along the rim to soak as much as possible. It fizzes and breaks up any rust or calcium. If we've gone a while between treatments, we'll leave it in overnight and go in a couple times with a toilet brush to agitate it and re-wet the rim and bowl. A light brushing removes any remaining deposits with ease. For shower heads, it's best if you remove them and soak them in a plastic or glass bowl. We place the head face down in the bowl and pour the CLR into the pipe fittingvto thoroughly soak the inside and clean any screens or diffusers. Fill the bowl enough to ensure saturation of the jets. Usually 15 minutes will do it, you can lift it and watch how the liquid flows out to confirm it's clean. You should see nice, even individual streams as the head drains when you lift it. If it dribbles or some jets are still clogged, just soak longer. We have oil rubbed bronze fixtures and the solution has not affected the finish at all. If you can't or want to remove the shower head, you can put some in a zip loc bag and tie it over the head in place. This works best for routine maintenance where it's not super clogged. You can do the same on sink faucets, etc. to keep the aerator clean and water flowing smoothly. Be sure to open any windows/doors and use fans to ventilate, this can harm your eyes and lungs. Rinse the whole shower well after this kind of treatment as it can break down grout over time. If possible, removing the shower head and soaking it outside is really the safest and right way to do it *NOTE: Be very careful when turning on the fixtures after treatment, especially if you used the ziplock bag method. This is an acidic solution that can burn your eyes and lungs and any remaining product inside the fixture will be sprayed out on first use. I have a rainshower head that always surprises me how much liquid can be inside it when turned off, and more comes out depending upon the angle you hold it at, this means you might have baffles that can hold CLR and disperse it when you turn the water on, even if you think it's empty. I've gotten some on my skin and washed it off promptly with no issues, but it could burn those with fair or soft skin if left on for any amount of time. I would imagine it would injure your eyes instantly. Be sure to rinse the fixture well before use and wash any residue off of sinks, tile or grout to prevent damage or staining. This is a great product but you have to be careful; wear gloves, eye protection and do not let fumes build up or inhale them. Keep kids and pets out of the treatment area to avoid any accidents.

Perfekt reinigt Kalk und andere Ablagerungen schnell und dauerhaft

Works great. My toilet had hard water stains calcium lime and rust. Made it look new again. My sink too. Great product 5 stars. Great seller fast shipping

Le pire produit, je ne comprend pas dutout les commentaires positifs, ce produit m'a coûté 88 euros, so efficacité est moins que celle du vinaigre, si vous avez du calcaire passez votre chemin, c est une pure arnaque

Great product works well

Excellent price and shipped fast.
