One splash, one wipe, and BLAM-O—those calcium and lime deposits that have been mocking you for months suddenly pack up and leave town like they’re late for the train. My faucet literally sparkles now! It’s borderline magical, yet undeniably real (I even pinched myself to check).If your bathroom tiles have been auditioning for the role of “worst water stains of the year,” prepare to see them transformed into shining stars worthy of a big Broadway finale. I’m telling you, one minute you’re shaking your head at the ugliest rust ring you’ve ever seen, and the next, it’s gone, off on vacation with yesterday’s grime.So if you’re looking to break free from scrubby misery and do a victory dance across your squeaky-clean floors, this is your golden ticket.

Don’t say I didn’t warn you: once you go “Calcium, Lime & Rust Remover,” you can never go back.

One of the best calcium and hard water stain removers I have found. There is not an overwhelming chemical odor when using. Got the hard water stains off my glass door and walls of my shower. I will definitely buy again and recommend to others. Worked well on sick and toilet as well.

We have very hard water at our place and it's always leaving water spots. This product gets rid of it pretty easily with very minimal scrubbing. Other than the not so good smell, ill continue to use this product.

Did the job well! I am happy 👍🏻

From kitchens to patios, CLR gets it done. This multi-surface cleaner tackles calcium, lime, and rust like a pro—on everything from shower heads and sinks to siding and glass. Fast-acting, EPA-certified, and bleach-free, it’s the safer, smarter choice trusted for over 40 years.

If you buy this product, be sure to have your own functional spray bottle to transfer CLR into. The sprayer attachments that come with tgis do not tighten or sit correctly on the bottle and CLR leaked out everywhere.

I have found the product of my dreams. Let me give you some background for this review. Twenty years ago, we installed a farmhouse copper sink in our kitchen. I love it; however, it has been a pain to keep clean. I know copper can have a beautiful patina but when it is your sink it always makes me wonder if it is clean. Copper has some amazing antibacterial attributes that make it wonderful for sinks and I love to see the polish of copper, but I have been struggling to find a cleaner that will work without me putting a massive amount of elbow grease into it. This is it. Twice a week I spray my sink down; let it sit and wipe it off with a cloth. I have a polished copper sink that shines. Thank you!

Toilet flush hole became clogged with lime severely limiting the power of toilet flush.Once the Lime was removed from the hole, monthly insertion of a 1/2 cup of CLR intothe toilet tank has eliminated Lime build up. Also, putting the kitchen sink sprayer head into aglass half filled with CLR over-night 100% unclogged the sprayed head like magic.Great product for lime removal
