CLR Brands® Calcium, Lime & Rust Remover, Blasts Calcium, Dissolves Lime Deposits, Zaps Stubborn Rust Stains and Hard Water Deposits, 22 Ounce Spray Bottle (Pack of 1)

Very effective product to remove any stains or build up areas in the toilet or sink. Just spray it on and let it sit for a few minutes, then rinse and wipe. All good.

Clean calcium deposits in our shower floor very well, just soak for a few minutes and the calcium stain came right off. Be sure to use mask since product is hazardous to breathe in.

This really works, held off on buying too long. could not get my tub clean with any other product or home-made solutions. thought my tub was ruined and uncleanable. squirted this all over. rubbed a little and let sit. tub now sparkly clean. good stuff. def 5 star.

I got this cleaner because I was dealing with hard water stains in my bathroom, and it worked really well. The spray bottle makes it easy to apply, and I noticed results almost immediately. It dissolved the calcium and lime buildup around my sink and shower with minimal scrubbing, which saved me a lot of effort. Plus, it works on rust stains too, which is a big bonus.One thing I really like is how powerful it is. I’ve tried other cleaners that barely made a difference, but this one cut through the tough buildup quickly. I used it on my faucets, showerhead, and even an old tea kettle with hard water stains, and everything looked much cleaner afterward. It’s nice to have a product that actually does what it claims.However, there are a couple of small downsides. First, the smell is pretty strong. It’s not unbearable, but I definitely had to open a window while using it. If you’re sensitive to strong cleaning smells, you might want to wear a mask or use it in a well-ventilated area.Another issue is that for really tough stains, you still need to do some scrubbing. While it loosens up buildup, it doesn’t always wipe away instantly, especially on older stains. I had to go over some spots more than once. Still, for a cleaner that tackles calcium, lime, and rust all in one, this is a great product to have on hand.

Perfect for hard water stains in the shower, just spray and let sit and even stubborn hard water stains and calcium build up come right off.

OMG, why did I wait so long to try this?? I grew up in the 90’s seeing these commercials all the time on tv and I had never tried it. I’ve had these tough stains on my tub that won’t come out. I even tried bleach and scrubbing and they wouldn’t come off. I finally bought a bottle today and sprayed it all over my tub and let it sit for a couple minutes. I scrubbed and sprayed water and almost everything disappeared! The harder spots I had to scrub a bit more but I’m soo impressed! The only thing I have to mention is that it did start making me cough so I had to open the window and turn on the fan. I’m also very upset that I am JUST finding out how great this product works. I’m guessing this is how everyone has been able to keep their tubs so clean.

Didn’t remove water marks or anything

Always a great product!!!
