Pro Calcium, Lime & Rust Remove - 1 Gallon

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.

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.

This product works well to remove stains over time. You can see results from the first use. It takes about 3-4 uses and the long-time stains are gone. The toilet is shiny and clean. It also can be used for the bathtub.

Amazon wants me to talk about THE EASE OF USE THE VALUE FOR MONEY THE FLAVOR, As for ease of use, I put it in a spray bottle, a few squeezes on the buildup and grime, walk away as its stank works its magic, Then use one or two more squirts to see if its done its thing, with the buildup I work against I don't even need to scrub, so for my use case, its VERY easy on the usage. The value for money is what I'm here for, if you put it in a spray bottle, and use it correctly this one gallon should really get alot of work done for darn cheap, I bought it to use specifically at work, and found out I have zero chance of reimbursement from my employer. And at this price, its absolutely fine, safety inspection on my machines pass with flying colors and its 3-4 spritzes after each task and I'm set till the next day. And the more you use it the better it works, takes older buildup that I thought was part of the whole machine and washes it down the junk trap. As for Flavor well it hurts my eyes to smell it, I hate my job a whole lot, but I'm not gonna taste it.

While white vinegar also works, it has a disagreeable odor. Unlike white vinegar, you can't leave this to soak on porcelain or it will etch it. But CLR Pro does work quickly to remove stains and limescale. Just be sure to thourally wash it away before it can etch surfaces.

so good, got out toilet stains from renters who never cleaned. toilet had been repeatedly scrubbed and still stained. let CLR sit overnight then scrub with a regular toilet brush, stains gone.

I really wish I had taken a before picture! We had about three years of mineral buildup on a relatively new toilet, and it had gotten really bad. It had almost completely filled the siphon jet and was also heavily built up along the bottom of the bowl. I drained most of the water out of the bowl and then filled it with 100% CLR. I let it sit for about 45 minutes, and with very little scrubbing, we now have what looks like a brand-new toilet again! Amazing! 👍

Bought this and the whole family uses it. Great value! Highly recommend!!

Perfekt reinigt Kalk und andere Ablagerungen schnell und dauerhaft

Excellent

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

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

The same quality as the smaller bottles but it saves you money purchasing it in the large bottle.
