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

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’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.

Tuff on rust stains and was better than other products I’ve tried.

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.

Best product I’ve ever used

Large container was dented.

We have a high amount of manganese in our water and would spend about an hour SCRUBBING the shower with other chemicals but with iron out I was done in less than 30 minutes with far less scrubbing. The showers look almost brand new again. The smell was kind strong but I wore a mask and opened the windows to help the smell.

I bought the 9.5-pound container because I figured if I'm going to declare war on rust, I might as well come prepared. This stuff means business. I used it on some stubborn rust stains that had been hanging around long enough to start paying rent, and I was impressed with how much of a difference it made. It’s useful for the bathroom, laundry, kitchen, and outdoor areas, so there are plenty of places to put it to work. The container is huge, which is great because once you start finding rust stains, you suddenly notice them EVERYWHERE. At this point, I’m walking around my house looking at rusty spots like a detective looking for suspects. Five stars. The rust has been officially put on notice.
