Generic Front 9 BARC Concrete Rust Remover 1 Gallon

This is the best rust remover for driveways and sidewalks that I have found. It outperforms others I've tried by 10x. The only issue is the cost. It's very expensive and does not go very far. A gallon (at $60-70) will barely cover a double car driveway.

When reading product reviews I tend to take with a large grain of salt those that are overly effusive in their praise of the "miraculous / amazing / out of this world" performance. Well, be forewarned, this is one of those review. But I'll back it up. I had an air conditioning condensation drain that clogged, resulting in the overflow drain pan constantly being full. Over time that pan rusted, and the drain for the pan dropped out over a small roof section over my garage. Over the months (years?) that left a nasty rust stain on my asphalt shingles. No damage to the shingles, just unsightly. I tried to clean the stain by hand with CLR (nothing), and even tried pressure washing it . . . carefully (I know, not a great idea . . . and it didn't work). So I started searching around the internet looking for something. I eventually ran across a video where the user praised the amazing job this BARC product did. Out of other ideas, I spent the money for a gallon (at $60 or so I sure HOPED it would work), and gave it a try. And the result is just amazing. I poured the BARC into a spray bottle and got to work spraying the stained area. The rust stain pretty much dissolved before my eyes. I stopped halfway to admire the change, and though the shingles were wet I could clearly see the red had disappeared (check out the picture). Well, I finished up the affected area and let it marinate for a half hour or so just to make sure it had enough time to do its thing, and then went back up and rinsed it off. In short, the stain was GONE! There are no noxious fumes, and my fingers didn't smoke and dissolve when I got a bit of it on me. IT JUST WORKED! I know it's pitched as being for rust stains on concrete (I tried that too and also works there), but it darn sure fixed my shingles stain. And the good news is, I have a lot left over for future cleanups. AMAZING STUFF!

It really works. I did have to do multiple treatments (3x) with a little scrubbing (with metal scrub) but the stain came off. It doesn’t seem to have very strong odor, pretty easy to use except for how expensive it is for one time use cause I ended up using the whole gallon. But I think it’s worth it.

This product was a total waste of money and very disappointing. I applied it according to the specifications and it still didn’t work. I watched a number of videos on how to apply F9 BARC, and they said to apply it on wet concrete, or even dilute it half with water. But this product said to put it on dry concrete and not dilute it. So after prepping the concrete washing it down, rinsing it off, letting it dry then I applied the solution with a pressure garden sprayer. I let it dry according to the directions and then I rinsed it off thoroughly and waited until it tried. The stains did not go away, so I repeated the process. I applied it three times, let it dry and then rinsed down each time after working it in with a scrubber according to the directions on the label, and it did not remove the stains and it etched the concrete. Do not waste your money or time with this product, get the authentic F9 BARC. The first two pictures were before treatment, and the last two pictures are after three treatments. It only made it worse because it etched the concrete. I also applied it twice on rust stains in my garage and it faded them slightly but did not remove the stains. Take my advice, DO NOT WASTE YOUR MONEY ON THIS PRODUCT! GET THE AUTHENTIC F9 BARC!

I used this for Iron fertilizer stains on the driveway and it does work pretty well. what really works good is to add a second coat after the first coat dries. expensive for a small area it will cover.

worked like a charm.... just amazing. Would certainly recommend it

This product is AMAZING! This is only an after picture. I cleaned my golf cart batteries and it left lots of rust. Power washed as directed, let it dry, put the solution in a spray bottle and WOW! Works fast.

Amazing product really remove rust stains . Try in concrete and pavers and worked like a charm. 10 of 10
