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

Living in Florida, rust stains on concrete are just part of life, especially with irrigation water. I’ve tried a handful of products over the years, and this one has been the most effective so far. The application was very easy: I used a pump sprayer to spray it on the concrete. I gave it a minute, and rinsed. No scrubbing, the ingredients create no fumes, and the rust disappeared almost instantly. It caused no damage to my concrete, but use caution if you have any painted surfaces. Read the label because I do not know how compatible it is with epoxies or paints. I used it on my driveway and patio. Everything brightened up like new and looks great. The photo shows an untreated vs treated area. The 2‑pack is a good value — plenty of product for my job. Also worth mentioning: the product arrived in excellent condition. No leaks, no damaged bottles, and everything was packaged securely.

This stuff is amazing! I sprayed the stains on my driveway & let it sit for about 30 minutes. When I went back to check, the rust stains were gone. Caution: it will kill your grass!

WOW! I had some pretty heavy rust stains on my concrete driveway and tried 3 rust remover products and Iron OUT was the hands down winner. I put it in a pump sprayer and sprayed the area. I let it soak for about 15 minutes and rinsed it off. Rust is gone! I wish I had taken before and after pictures so you could see for yourselves how well it worked.

My sprinkler system has rust and leaves my driveway stained. This rust remover works fairly well. It removes most of the staining. However, some spots require you to use a second coat of spray. The product is easy to use.

High iron in the well water. Rust looking stains on the patio block, flagstone, cedar siding, and downspouts. Stains had been there for a year. Sprayed the product on and within about ten minutes the stains were completely gone. Amazing!

Absolute garbage!! I don’t even want to give it a one. It ruined my concrete and never took any of the iron out at all. Worse part is I have a grad party Sunday.

it works great ,it is what is says i have used 3 bottles to remove rust from porch , sidewalk, driveway, it is fast no work i have a little machine shop, and I track a lot of metal dust and particles all over, and it is the best thing that lives up to what says

Made the plunge ($$) and renewed my 50+ year old concrete driveway as I was getting tired of looking at the old one!? Anyway, after the demolition, framing, pouring & curing, the new driveway looked GREAT, so much so that you had to wear sunglasses while out on it on sunny days. Then the summer rains came, and everything changed around the gutter discharge. I felt like someone had "keyed" my brand-new car!! Rust residue from the gutters made a trail of brown that was ultimately tracked to many roofing nails long abandoned and rusting from several roofing jobs over the recent past left there by the contractors instead of disposing of them properly. Took care of that problem, personally! Purchased Iron Out liquid Rust Stain Remover from Amazon and the results were mixed. Applied the liquid according to directions on the gallon plastic jug after shaking it vigorously to ensure the ingredients were well mixed. Had enough product for 3 applications and the photos show the results of "blotchy" driveway area. Even used a scrub brush with the grain of the concrete on 2 of the applications and still no better results. Maybe I will let the summer sun try to bleach it out or try another product to see if the results will be better.
