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

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.

That is the best for iron in toilets water. Dissolves the rust immediately. Have also used it on white clothes for iron stains. You have to monitor otherwise the decorative colors will be faded out. Best product on the market.

My washer was brand new when I purchased it. We have well water, and the water leaves brown, rusty buildup all over the inside of the detergent dispenser and the fabric softener dispenser. This Product is a miracle for real !!! recommend

I cannot believe the power of this stuff. I bought a house that was vacant for 2yrs, the home has well water(In Florida). The water softener and filtration system was severely neglected but functional and recoverable. The toilets were straight just rust color. I tried so many products to clean the toilets because I had bigger items to tackle first like HVAC and electrical. It literally took one treatment directly to the toilets to restore them back to brand new white shiny porcelain, I absolutely was astonished. I added to the salt tank and forced a regen and immediately saw results through the see through filter reservoir as well. Now that I have a complete understanding of utilizing this product and the salt, it clearly will be a short term recovery of the water system that I was told was a "must" replace item. This will also help clean up all plumbing pipes. Absolutely amazing product.

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.

Large container was dented.

Have hard water? This is the only option. 12/10.

we just moved into a new area I had no idea about iron in the water. I washed my first load on whites I added bleach like I normally do, and my entire wash looked dingy and almost had a reddish color to them. Freaked out looked thru the load thinking a red item must have been in there, NOPE! washed again this time with more bleach thinking that will fix it...WELL it was worse my whites were almost orange...my favorite shirt that was crisp white before being washed was now orange in color. I had to dry them as I did not know what else to do I had other Laundry to get done-after hours of research I found out it was the iron and iron does not like bleach it almost works as an agent to bring out the iron that is masked in the water...SO fast forward two weeks I found this and its amazing IT WORKS. I put it in the drawer for my front loader with whites NO BLEACH and it whitened them. now i rewashed all the other stuff I had dried and it helped but not sure they will ever return to their normal color. I used the pre-soak setting and put it right in the same tray as my detergent. I was a little worried about chemicals being on my bath towels and socks so I re-rinsed them. I hate to have to use this but its the only thing keeping my whites, white... otherwise I would have orange socks and towels

Perfect!

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.

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

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.
