Really, really worked. Most of the rust came off first time from the toilet and just went over it again to take off the last traces.

Excellent product...will buy again

Good product worked well

I must for high iron water for your toilets for your softener for everything really!

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.

Good product, helps to clean well

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.
