Iron OUT Powder Rust Stain Remover, Remove and Prevent Rust Stains in Bathrooms, Kitchens, Appliances, Laundry, and Outdoors, 1 Pound 12 Ounce

UPDATE - I did add some to the wash, following package directions, when I washed my cloth shower curtain with rust stains from hard water near the bottom. Up to then, nothing else had worked. One was and the stains on my white cloth shower curtain were gone.ORIGINAL REVIEW - I purchased this to clean, and hopefully prevent, iron stains in my bathroom toilet. The inside of the tank was almost black from 65 years of accumulated rust stains, and the stains leached into the bowl, causing dark streaks running down the inside of the bowl. It seemed as soon as I cleaned them, they were back.I purchased this product in the hope that if I could clean the rust stains from the inside of the tank, it would keep the bowl from staining so quickly. I had read it would make the inside of the tank look white, again, almost like new. I was skeptical.But it does work VERY well. I followed the directions and put 1/2 a cup of the powder into the tank just before bedtime. The next morning, when I looked in the tank the water was very murky. I flushed a couple of times and saw that the sides of the tank seemed slightly lighter, but still very dark. So I repeated a second night. The next morning the water was not as murky as the morning before, but still quite dark. I decided to brush the inside of the tank, for good measure. After that, the water was as murky as the day before. However, the inside of the tank was now a very light gray.So I repeated the treatment for a third night. That did the trick! The stains are now all but gone. The inside of the tank is an almost-pristine white, and in the week since I finished cleaning it, the bowl has stayed a pristine white. Now I can’t wait to try it for removing the rust stains from the bottoms of my cloth shower curtains. Nothing else I’ve tried to date has worked.

Really works!

Works well on iron stains, removes them completely

I am sure this product works for some, my experience was a no.Have a rust ring around the drain in my bathroom sink. At least I think it’s rust. I followed the directions on the bottle and did not have success in removing the red/brown ring. It’s possible that it’s lime scale and this simply is the wrong product for what I need.I am not knocking the product, simply sharing that it didn’t help in my situation. I knew it might be a gamble getting it, so am not heartbroken over it.

I have used IronOut for toilets, sinks and laundry! I whitens everything by getting the rust out.
