Iron OUT Rust Stain Remover Powder, 9.5 lb. Bottle

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.

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.

I have used this product for years and find it works great to reduce iron stains on my white clothes clean iron stains on the toilet sinks and dishwasher Highly recommend it if you have iron in your water

Excelent product. I never have my toilet more sparkling than that I love this product highly recommend for everything

Iron out works. I used in the back of my stool. Left in over night and the rust was gone the next morning. No scrubbing.
