CLR Calcium, Lime & Rust Remover, Blasts Calcium, Dissolves Lime, Zaps Rust Stains, 28 Ounce Bottle (Packaging May Vary)

great product. works well.

Used the product to clean rust and calcium build up on toilet and calcium deposits on sinke/bathroom faucets and showerheads. IT WORKS! I should open a college appartment moveout cleaning service just for this purpose!Used this product for 3 major cleaning projects of college student bathrooms during moveout over the last 3 years in order to help them save a heafty cleaning deposit. These apartments generally do not have soft water SO rust/calcium build up is atrocious. How these kids live with the unsightly MAJOR RUST in the toilets is unfathomnable but guess they are busy getting an education, not worried about the rust/calcium buildup. Once I am finished with the bathroom, IT IS SPOTTLESS and so shiny! Every time I have completed the project, I wish I had before and after pictures. NEXT TIME FOR SURE!DIRECTIONS: Follow them. I use thick vinyl gloves in all cleaning projects. For the really really rusty/calcium build up, I dont dilute the product. Depending on how much build up of rust/calcium there is, you may need to extend the product contact time. Then, scrub using old rags, scrub brush and for those hard to get at places, an old tooth brush. Then rinse or flush. Repeat as needed.A hint: you know the product is working when you start to see it foam on the rust or calcium.THIIS PRODUCT IS AMAZING!.

Works ok if you let it soak

great product, so far it worked better than anything else by my faucet in bathroom

This is the only thing that has been getting rid of the lime stains in my toilet bowl. The directions say to empty the water out of the bowl, but I don't know how to do that so I've just been pouring some into the bowl, wait a few hours and scrub and flush and little by little the lime is going away. Highly recommended.

This CLR calcium remover works great. I have used this product a few times over the years. The bottle is easy to handle. The product pours out safely and does not splash. I love that the product works extremely well. I am very happy with this CLR calcium remover.

I posted a review a few days ago and it's been removed. So I'll keep posting until it sticks.I noticed a few months in I started getting rust stains on the driveway beneath exhaust pipe.I bought CLR twice, (two applications, followed instructions and it didn't work. Later, I did some research on Youtube and it seems others had the same experience.I'm giving it 3 stars b/c it does work a little for light rust on hand tools (screwdrivers) etc, (decided to try what was left on those, as I didn't want to "waste my money" but as far as the driveway (the reason I b ought it) just didn't work.

I’ve used this for awhile for my sinks and toilets and works well.I was looking up where to buy this the cheapest, and found a review that talked about using it for the dishwasher. Now, I live in an old apartment so I have no control over the pipes and old dishwasher. All the dishes have a lovely hard water film over them. I bought the Lemi-Shine dishwasher boost, the dishwasher cleaners, and different detergents all with minimal results. I thought it was hopeless, and chalked it up to hard water and old pipes. Decided to give this a go. After the first cycle, looked like there was still residue so ran again. When I went in, there was a powder on the heating coil so took a towel and wholly cow so much orange residue came off. Wiped down the whole inside with CLR to make sure that like the spraying holes and all were cleaned. Then ran a empty cycle to rinse it out.I was shocked after the first set of dishes came out. I didn’t tell my boyfriend, so he said brought one of the glasses to me when he was unloading because he was shocked and confused. It worked sooooo well!! You can see in the picture on the left is one that hadn’t been run yet, and the right is after running. This is with no extra additives or special detergents either. I thought there was no hope, but this stuff is amazing!!!!!
