Lime OUT Heavy-Duty Rust, Lime & Calcium Stain Remover, 24 Fl Oz

I've tried many different kinds even more expensive ones, but this one was the only one perfectly works. I empty the tank and leave this liquid for 2 hours and after that cleaned by hard brush. Because this stain was for several years, I had to redo it twice and make sure brush it hardly. Thanks so much. This was the only product finally worked . I will only use this for rest of my life

Only thing that cleans out the rust in toilet. Be sure to turn toilet bowl water off under toilet %26 flush. Then pour 1/3 of bottle in toilet %26 let sit overnight. Letting it sit longer will clean out the pipe you don't see so it flushes normal %26 no longer slow. May have to repeat to get all stain out.

follow the directions and it works as exactly as stated.

I have hard water at my home and my dishwasher had gotten disgusting. I cleaned with this product and it has my dishwasher looking brand new. I did mix with bleach and it took my breath away so don't mix this product with bleach. It doesn't need to be because it cleans better on its on. But I had a bright idea to disinfect. I give this product an A+

This product works great for clearing the toilet bowl, and is easy to use.

Took this lime right out of my toilet and I put some in the tank. Also love it.

Removes stains with no scrubbing needed ! Toilet ring went away as soon as the brush touched it ! Rust stail in tub disolved down the drain !

I found this one time at Walmart. They have never had it since then. I also found it one time at the Tractor Supply Company. I don't understand this. We have used Lime Away and CLR. Neither work as well on rust, hard water stains or the black marks on our white sink from washing aluminum pots and pans. I finally gave up and ordered an ample supply directly from the manufacturer. It is reasonably priced and just plain works!

It removes most scum and mineral build up. there are a few faucet/shower heads with a lot of build-up that it didn't remove on the first try. it may take several applications of Scum at full strength. it did work everywhere else, though, where other products had failed.

A useful adjunct for removing lime scale caused by hard water.
