CLRCalcium, Lime & Rust Remover, Blasts Calcium, Dissolves Lime, Zaps Rust Stains, 28 Ounce Bottle (Pack of 2)

My tub had some rust and a coat of grime on it. I filled the tub with hot water and added one of bottle and it made it like new!

This is a great product!! My quartz countertops are a matte finish, and due to the hard water where we live, I’m always struggling to clean the white scale that builds up behind my kitchen faucet. I’ve tried every kitchen product out there, and none of them work. Enter CLR, which I thought was only for cleaning out clogged pipes. This is a different product than the one for your pipes, so be sure to use the right one. It still takes a little bit of scrubbing, but it DOES remove the white calcium buildup on countertops and faucets.

I used this at the base of our toilet bowl. I ended up using a whole bottle at at two consecutive times and a lot of elbow grease. It took a lot of scrubbing but it was really crusted so all in all if we had done this sooner it would have been great

Good cleaning product overall for faucets, etc

First, allow me to say that I did not taste the product. I'm fairly certain that this is one of those, "don't lick that" products. But Amazon wants it to be rated on flavor. Please, Amazon, I'm a Millennial. It's Gen Z that eats the tide pods.Anyway.I have very hard water in my house. One hot shower and there's rust stains on the wall. It's bad. As a result, every year or so, the float on one of the toilets starts getting hung up, which means the toilet just keeps running. At first, I thought the float assembly just needed to be replaced, but on a whim, I decided to try this first. It was a fair amount of trial and error. I didn't want to risk eating through the float assembly, which had been replaced earlier with something cheap, but I also didn't want to waste product. So I turned off the water to the toilet, drained the tank, dumped a bunch of CLR onto the offending part, and let it sit for 2 minutes. Then I diluted the daylights out of it and let it sit for about an hour. Turned the water back on, flushed a few times to rinse thoroughly, and found that my problem had been resolved.I did have to crack a window to prevent the fumes from being overwhelming, but other than that, I have no complaints.
