Generic Front 9 BARC Concrete Rust Remover 1 Gallon

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 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

Read all the reviews, watched all the videos, followed instructions completely. Don't believe the coverage for one gallon. instructions state to apply liberally with hand sprayer. I applied moderately and was out of product in 140 sq ft. It lightened the stains by about 20%. My slab is 240 sq. I'm sure it would be good for rust stains but useless for deep fertilizer stains. At $50 a gallon to apply 2 coats it will cost me $200 and I don't believe it will remove the stains to a satisfactory level. $15-20 a gallon and I wouldn't have written this review. I will add photo's.

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.

It took the rust right off. Did not have to brush or anything. Great for rescuing cement.
