Iron OUT Rust Stain Remover Powder, 9.5 lb. Bottle

I have to say....IT WORKS. After kaboom bowl blaster discontinued its product, I have tried so many toilet cleaners to get the bowl white again. So if you figure how many yrs of buildup, that should tell you what my toilets looked like. Also, I can't tell you how much money I have spent trying different toilet cleaners. My friend found this at one of the hardware store in a small bottle. Neither of us thought it would work but we tried it anyway. We both were blown away when it worked. Really blown away. I had white toilets under the build up. We couldn't believe it. We didn't even have to scrub it. I highly recommend this product. I do have to say though, different areas have different stains so I can't say that your area stains can be taken out. We live in outback Wyoming so for this area it works great. My friend took her bottle home to use on her toilets and it worked on hers too. I ordered a big jug of this stuff and will order more next month and the month after that so I don't run out in case they discontinue this product. Thank you for such a good product.

This stuff is awesome! Toilets in a new construction were completely brown from well water with high iron content. They are now white and look new - all stains removed. The size gave an amount more than enough to thoroughly clean five toilets - tanks and bowls. There was no need to leave anything soaking overnight. I flushed the toilet to get the total inside bowl wet, sprinkled Iron Out on the bowl stains and it started to bubble and clean instantly. I just poured an amount around the inside of the fully filled tank. I applied a heavy amount to each toilet bowl (approximately two-thirds cup initially and second treatment of one-half cup) and tank (approximately one and one quarter cup initially and then second treatment of one cup). I treated all toilets twice with a 20 to 25 minute wait time and then scrubbed with a toilet brush after letting it work. Be sure you have good ventilation after putting this in the toilets. You need to ensure you are in a ventilated area while even pouring the powder into the measuring cup. Pour slowly to reduce the powder mist.

I have used Iron Out for years in Florida along with salt to regenerate our water softener. I have also used to remove leaf stains from our concrete pad & hard water stains from our toilet bowls. Each application worked for us. It can be pricey but, I always keep it on hand.

IRON OUT works like magic! It instantly removes the toughest rust stains, as well as hard water stains. It is a bit pungent but works like a dream. I even use it in my pool to clear cloudy water. I am never without it!

I had bad rust stains on my patio. I used it 4 times on the same spots, every time more rust is coming out, I am afraid I might damage the concrete if I use it more. I still have rust stains, so I will try again. It works.
