Review: Incredible - Rarely rarely and hardly never write a review. I've lived in my home, everything pristine and new into an area with incredibly hard water. Tried various chemicals over the last 25 years and nothing seemed adequate in even touching the rust stains in the shower. Yes I do have a water softener and shortly use the rust out salt in it. This stuff diluted 50/50 with water worked so good. I sprayed it on, waited not even a minute and used a body scrubbing rag just lightly rubbing it in and then rinsed off. I've included some pictures to show the after and so sorry I didn't take any of the before. But you couldn't see thru the glass at all and the walls were so rusty stepped out was so embarrassing for anyone to see. So judge for yourself and write with any questions and I'll try to respond to anyone. Thank you CLR for an amazing product.
Review: Works great and a more economial size - 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.

### ⭐⭐⭐⭐⭐ This Thing Really Works!
*by T***K on January 2, 2024*

My cleaning journey - I have 4 toilets with a significant buildup of streaks around the bowl due to the hard water in our area. These streaks and rings in the bowl are aweful; it looks like the bowl is rusted. I was away for a few months, so the toilets weren't flushed regularly. I have tried all kinds of chemicals to remove these streaks to no avail, even the standard CLR product. I saw the pro version, so I decided to try it. At first, it wasn't doing anything better than other chemicals. I discovered that letting it sit in the bowl for a few hours would break down these hard calcium streaks. I can see fizzles at these streaks as the Pro CLR attacks them. So, I decided to soak the bowl for 24 hours to allow the chemical to work longer. I returned occasionally and splashed the Pro CLR onto the streaks to ensure they continued attacking them. And sure enough, after the soaking period, the hard buildups began to loosen up a bit, enough that a hard scrubbing could remove some of it, but not completely. I then use the pumice stone to scrape off what's left over. That did it! Soaking with Pro CLR and scraping with pumice stone thoroughly cleaned the bowl. It was a lot of work and elbow grease, but I can now declare that my toilets look brand new again. The lesson here is to flush the toilet regularly to prevent hard water buildup. If the toilet is not going to be used for a long time, turn off the water to the tank and drain out the tank so there is no chance of water leaking into the bowl. You would empty the bowl except for leaving a small amount of water in the bowl to prevent the smell from your sewer line or septic tank. Then, pour the Pro CLR into it and let it sit. When I travel again, I order a gallon of this stuff to put in the bowl. No more buildup when you get back.
