Lime OUT Heavy-Duty Rust, Lime & Calcium Stain Remover, Multi Purpose Cleaner, 24 Ounce,

A few months ago, I spotted a low price for this product on a deal website and -- since I'd recently noticed a stubborn ring of limescale in my toilet -- placed an order for it. It was scheduled to arrive a few weeks later, but Amazon said that it wouldn't arrive then and I could cancel or wait. Given the positive reviews that I saw, I decided to wait.It finally arrived a few weeks later and I gave it a try this morning. I read the (slightly frightening) instructions, found something pointy to open the flip-top spout, and gave the bottle a few healthy squeezes to dispense some cleaner around the bowl. The instructions said to let it sit in the bowl for a while, so I closed the flip-top cap and took a shower. (I guess I expected it to be more "gel" or "cream" like, but it was pretty "liquidy". Not a problem, just surprised me a little bit.)When done, I gave the bowl a few hearty scrubs with a toilet brush and the scale appeared to be gone. I figured if it did such a good job on the water-line scale, I should use the solution to scrub the entire bowl and under the rim, so I spent a few minutes really cleaning things up. I flushed and noticed that some of the blue dye remained on the bottom of the bowl, so I gave those areas some light scrubbing and when I finished, the toilet looks almost brand new.I'm usually not a fan of cleaning with harsh chemicals, so I'm going to dig a little deeper into the ingredients to see if I can effect the same results with something gentler like citric acid crystals, but -- other than the possibility that I'm dumping somewhat harsh chemicals into the sewer system -- this product does exactly what it says it will do and if I can't mimic it more safely, I can see continuing to use it.

Worked really well on mineral stains in toilet.

easy to pour but way too liquidy. does a good job with most of my rust stained bowl and shower but some scrubbing is required. Lime Away is a jel and there is no scrubbing making Lime Out only a close second as capable of removing rust stained bowl and shower stalls. Lime Out is much better priced. Overall it is a very good product if you don't mind or are physically capable of a little elbow grease.

Love this product!!

Really good for for cleaning

I used this for my fish tank because there was a white crust build up around the whole inside of the tank, on the top where the water level was. I soaked the calcium build up with the lime out for hours then tried to a scrub it off and it did help a little but not entirely. I had to buy a metal algae scraper from petsmart and used that to scrub the build up off and I got about 12 inches of the white crust off before the metal scraper started getting dull. So I went out and bought a real glass scraper from Walmart, and also bought extra razor blades. Though I did not use it yet, I am positive that the blade will work! It's just more manual labor for me.

I had the worse stains in my toilet , they were black and green and peeling off. Sure I was able to get off some with the brush, even with bleach tabs, but there were yet ugly patches and streaks I couldn't resolve.Until I tried Lime out.The rest is history. Mic drop.

Nothing works better on toilets that I know of.
