Iron OUT Liquid Rust Stain Remover, Pre-mixed, Quickly Removes Rust Stains from Concrete, Vinyl and Other Outdoor Surfaces, No Scrubbing, Safe to Use, 1 Gallon

Very impressed, did not think I would be able to get the red stains out of the toilet bowls. Wow, it looked like brand new after 1 st use. I did use a 2" scrub brush on a cordless drill with a bit extender!

Excellent! Easy to use, great results.

We live in Florida and the water stains everything and finding this has been greatest ever. I put in spray bottle and spray area and yellow stain is gone, no scrubbing needed !

The product works great and we used it on a concrete patio and concrete sidewalk that had been rusted from the irrigation over many years.We used it by pouring it straight out of the bottle and also by putting it in a spray bottle. In our tests we found that the spray bottle worked but required 3-4 applications by spray bottle compared to pouring a healthy amount straight out of the container.When you pour it out of the container it allows a thicker layer of Iron Out to remain on the surface and act longer than just spraying. It also worked more evenly than spraying which often caused splotchy results.To do the entire sidewalk in front of our house (approx 40-50 feet) we'd probably need 3-4 containers.We also tried it on our vinyl siding where the irrigation was hitting the house and it worked really great from the spray bottle. Definitely recommend the product but make sure you are applying it in enough quantity on porous concrete surfaces.

This product does not work as advertised. My home has a rust stain on the front step, where the previous owner had kept a planter, obviously with some metal in it. Scrubbing, bleach and all the other little tips I found did not touch it. When I found this product, i was very excited. After using the product three times and noting that it did not touch the rust stain, I gave up. I purchased a very expensive rug to perfectly fit the front step and conceal the rust stain. Unfortunately, the first time it rained something about the product allowed the rust stain to bleed through onto the new rug. So now I not only still have the rust stain. I am not able to conceal it with a rug. This product should be taken off the market for false advertising.

the smell is HORRIBLE!! but it does such good work!! use it in a well-ventilated place! not recommended in home.

I had been soaking a rusted license plate in vinegar to remove the rust before repainting. An amount of this spilled on the concrete garage floor and wasn't discovered until it had soaked into the floor. Followed directions on this producted and even after 3 separate applicatons (floor allowed to dry betwen) this stuff has only lighten the stains somewhat. So, I would not recommend it for tough stains.
