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

Super ez to use and 100% effective! Poured it directly from the gallon jug onto the rust left by a dumpster on my pink brick driveway pavers and watched as the rust just disappeared!!!! I used a a scrub brush on a few slightly stubborn areas. Very satisfying clean up job! Pleasant smell as well! Highly recommend!!!

Completely removes iron rust stains from concrete plus golf cart battery leaks.

I used this on my driveway to get the orange stains out. It works but if you roll it on it will streak. I tried spraying it but wasn't enough. Seemed the best way was to throw it on and brush with a broom. It did lighten the orange but made stains at other places for some reason. Sprayed a third time and it left white spots and dark stains which I could not get out. Very uneven color now. Disappointed.

Had lots of rust on my curbs after record rainfall (they say it comes from rebar in the sidewalks) Applied this product with garden sprayer, per instructions. Within minutes the rust was gone. However, it left the concrete where the rust spots were much whiter than the the rest of the curb. Re-applied the product with sprayer then used a fluffy 4 inch paint roller with pole attachment to spread it over all concrete surfaces. A little goes a long way. Absolutely great results. Needed 2 gallons, but well worth it

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 only thing I’ve been able to find that works and takes no effort at all. Spray it on and watch the stains disappear.I did have quite a few dark spots that took a few applications but there was no scrubbing involved!

Great product. It works as described.

The product act like bleach. The product will bleach every thing white. I do not recommend for oil or grease stains. You will do more damage to the concrete or pavers. I recommend Dawn or laundry detergent to pour directly on the stains. Using to this product is hard to remove the white stains. It may be good if you are doing the entire concrete or pavers to match the color.
