  • Super product!
Size: 76 Ounce (Pack of 1)
Great stuff! It saved a toilet in my son's house. The toilet was rust stained, a gray and rust stain. His MIL had tried many things to clean this toilet. No luck. I poured some of this in, and the water roiled as it worked. Very cool! An hour later, I checked and it was mostly white. Just at the bottom it had gray scratch marks. Later, he poured a bit more in, and must have scrubbed it, as when I saw it next, it was all white. It's so easy! Pour it in and it cleans it. At my house, we have rusty water. We have a water softener that gives us clean water, but the house was empty for months and the toilet upstairs was seriously rust stained. I tried a pumice stone, and Barkeeper's Friend, and something else. None of those worked. But this stuff got it white. I just remembered something else. You want this is bit above the water line, so flush toilet, then line along water line with toilet paper, then sprinkle Iron Out on the moist toilet paper. Come back in an hour and expect a clean toilet bowl. Update: Today I added spray iron out, great addition! I got most of the bowl clean using above methods--flush toilet, lay toilet paper above water line, sprinkle in Iron Out, scoop some of it up onto toilet paper. Wait overnight. Flush. I was left with rust stains high in the bowl. I sprayed Iron Out in that area and scrubbed with a heavy duty green sponge. The rust stains came off! You can get under the rim with your sponge too. There are some excellent videos on YouTube about Iron Out taking on dirty toilets. I like my method better because: I did not shut off water I did not plunge I did not fill bowl with hot water--which can crack your toilet bowl. Hurray for all of us for getting rust stained toilets white again. ... show more

  • Does its job, even on old, set-in rust stains.
Size: 76 Ounce (Pack of 1)
I have "city" water, but I had started to get brown, rust-like stains appearing here and there on my white towels, like what I would see years ago, when we had well water. These stains would would not come out with any of the stain removing products, home remedies, bleach that I used. I was very upset, because the stains were ruining my expensive towels. As a last-ditch effort, I laundered the towels with some of my old Iron Out, using it as directed on the bottle. It complety removed all of the brown stains (the towels in question had been washed and dried repeatedly, so the stains were set in), and afterward, I made an effort to immediately remove the towels as soon as the cycle finished to prevent more stains from appearing, as I think my old washer's drum is rusted and it is what is causing the issue. You only need half a cup, and while the product doesn't smell good, you can toss in a pod once the whites have soaked for a bit, and they'll come out smelling as they usually do. ... show more

  • Great stuff for many uses.
Size: 76 Ounce (Pack of 1)
I have been using this product for many years. Ignore the hysterical review here by someone who apparently thinks Iron Out is all but radioactive and will kill you instantly. Of course, you use some common sense but I have put my hands in this stuff when dissolved in water and experienced no ill effects at all. Anyway, I thought I would mention a couple uses for this product that hasn't been mentioned here as I write this: 1) Dissolve a cup or so in warm water and pour it into the brine well of your water softener periodically. Water softeners are not designed to handle iron but they do remove a bit of it. However, if you have high iron content in your water, your water softener will experience a build-up in the resin bed. So, once a month or so, pour some in your brine well and run a regeneration cycle. It does wonders! In fact, if you have a water softener, your manual will probably tell you to do this, if necessary. Iron Out is the same product that iron reducing water softener salt uses. 2) Last year, my well started pumping very rusty water for some reason. Nearby construction may have disturbed something down in the well. I dissolved about five pounds of Iron Out in a 5 gallon bucket and poured it down the well. I let it sit for a couple hours and then ran the pump intermittently for a while to get the Iron Out into the delivery pipe and also to churn it up at the well pump. After a couple hours, I turned on the hose outside and it pumped out very rusty water. I ran it until it ran perfectly clear. It really broke up and cleaned out the rust. This isn't related to this product but I then purified my well with bleach, which should be done periodically anyway, if necessary. I then ran the water until there was absolutely no bleach smell. Even so, I had saved several large bottles of water for drinking for a day or two. The bottom line is that this procedure can work wonders and the Iron Out is what really got the rust and iron build-up out of my well. ... show more

  • Iron Out Works!
Size: 76 Ounce (Pack of 1)
We have very hard water, i.e. we have a lot of iron and other minerals in our water. It builds up over time and makes our sinks and other fixtures a terrible reddish, rust color that looks unclean. Scrubbing with regular soap and other detergents does not get it off and if it does, it's the "elbow grease" of the scrubbing itself. We use Iron Out to bring our fixtures back to a clean, natural color. We use it in sinks, in the dishwasher, toilets, and oiur water softening system filter. I have to say, the stuff really stinks! You really do not want to breathe it in and it should be used in a well ventilated area. However, it is very easy to use. I usually soak things first, for example, fill a sink with water and add Iron Out and let it sit for 30 minutes. After the 30 minutes, a quick sponging off will usually result in a clean sink. For really bad stains, a second application may be necessary. For a dishwasher, I just run Iron Out through a cycle and the dishwasher comes out sparkling clean! We use a lot of this and I wish it were a little more inexpensive, but it does the job and I guess that's what really counts. I am very pleased with the results I get from this powder. (This is my HONEST opinion. I was NOT paid nor compensated for this review in any way.) ... show more

  • Great for white laundry...
Size: 76 Ounce (Pack of 1)
Finally! I tried this by adding to white laundry but I have bacterial or live iron in my well water and they still would come out with orange tint. Then I remembered an answer to a question that was still there in Q&A. She said she just put the whites in a tub with water and Iron Out and let soak for a day then put all of it water too in washing machine and it all came out white. So I got a large storage container/tub and since my water is so bad I use distilled water apprx. 6 gallons, it would cost just as much to use a laundromat plus the hassle. I let it soak 3 days then into washer with detergent that has no whitening agents in it and no bleach, washer adds very little water since all water in tub goes in. To be sure I add about a cup to rinse cycle, as soon as it's done put in dryer. They also make a version just for washing white clothes only, if your washing machine tub is stained with rust just use that on large cycle 1st no clothes = no more stain. Also use a bit of the regular in toilet tank and bowl each flush, no more bacterial iron slime in tank and cleaning bowl is easier. It's good stuff! ... show more

  • Super Iron Out is great for cleaning mineral specimens
Size: 76 Ounce (Pack of 1)
Many self-collected minerals from Quebec, Ontario, and northern New York are iron-stained as they come out of the ground. After soap and water, if there are still brown stains on silicates, Super Iron Out works wonders. I usually cover the specimens with water in a nonreactive Rubbermaid or Tupperware-type container with a lid to seal in the odor. I most often start with warm water, sprinkle in a couple tablespoons of Super Iron Out and then leave them overnight. In the morning, I carefully change the water with running hot fresh water and then add a liquid dishwashing detergent (I tend to like Ajax because it doesn't smell much). After giving sturdy pieces a quick scrub with a soft toothbrush, I use my Albatross 500 water gun to remove the remaining clay, etc. from little holes and crevices. If there are biologicals like lichens or roots, a soak in slightly diluted Chlorox does wonders. Generally I find that feldspars, amphiboles, pyroxenes, garnets, quartz, wollastonite, scapolite, titanite, and most other silicates are not changed by this procedure, except for losing their iron stain. Fluorapatite doesn't seem to be affected if it has high luster. Don't use this on goethite ps. after pyrite since the goethite will be dissolved away. Crystallized hematite is unaffected if low concentrations are used. For localities of specular hematite xls, the clay and mud that gets caught between the blades is freed up by short treatments with Super Iron Out and then a soft brush or a water gun does wonders. Calcite doesn't like Super Iron Out. If it is a weathered surface, e.g. Grenville Marble, it cleans it nicely, but makes the surface luster slightly more dull, i.e. from dull to really dull. Lustrous calcite xls are ruined by Super Iron Out. Fluorite xls are dulled slightly, but only slightly by this treatment. If it's iron stain or slight dulling, I usually choose slight dulling. Super Iron Out replaces the older Waller procedure with sodium hydrosulfite, sodium bicarbonate, and sodium citrate, works just as well, is much cheaper, and much, much easier to obtain. ... show more
