Iron OUT Powder Rust Stain Remover, Remove and Prevent Rust Stains in Bathrooms, Kitchens, Appliances, Laundry, and Outdoors, 9.5 Pound

I hit the jackpot, did not expect. Perfect job, it does miracle. Removed the color in water tank like a magic. The aroma is bad but the job is excellent & that’s what its for. Worth the money. It’s all you need.

I’ve tried several rust removers over the years, including the more expensive leading brand, and this one performs just as well—if not better—at a noticeably better price point. Living in Florida, iron and rust are constant issues. I use this regularly in my water softener pre-filter system to manage iron buildup, and it does an excellent job breaking down residue without excessive scrubbing. It’s also been very effective in toilets where iron staining can get stubborn quickly. One area where it really impressed me was around the pool deck. We had rust stains forming from metal screws in paver areas, and this removed the discoloration without damaging the surrounding surface. I’ve even used it carefully on antique piano hardware and metal components, and it cleaned oxidation without being overly harsh when properly diluted and monitored. A few notes for best results: Follow the dilution instructions. Ventilate well (it has a strong odor). Test on delicate surfaces first. Overall, this has become my go-to rust treatment product. Excellent performance, versatile applications, and better value than the big-name alternative. Highly recommend.

This is the best at removing rust stains anywhere on anything. It is easy to use and works quickly with minimal effort.

This stuff is amazing! I have very hard well water & older house with rusty pipes. I have tried other rust busters but none have worked like Iron Out. I followed directions, put in my toilet, and it looked like a new toilet when I was done. All the rust was removed. It is really effective on rust. I got the big jug of granules, which I like. It doesn't seem to have a smell. I am going to continue using Iron Out, it's the only thing that works for me!

This stuff works great. I use it in my water softener to clean the base. Just sprinkle a cup of powder down the tube and 1/2 gallon of water and press clean. Works great

Works great for cleaning water softener, mix about one cup Iron Out in a gallon of warm water

worked pretty good considering how bad the stain was

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.

Perfect!

Yes, it works well with our well & septic system.

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.

J’habite les Laurentides et j’ai un puit tout neuf … avec du fer en tabarn … J’ai utilisé Iron Out et … Wawww … tout est parti sans frotter. Prochaine étape, je vais rincer mon puit avec Iron Out ( sans consommer l’eau pendant quelques jours ) … j’espère améliorer la qualité de l’eau … sinon ça aura au moins nettoyé les conduites.
