Generic Front 9 BARC Concrete Rust Remover 1 Gallon

We have previously used the F9 BARC cleaner to remove rust and other stains from our concrete porch. The results have always been very good and better than other products we have tried. The cleaner is easy to use and mixes readily with water.

Our golf cart batteries leaked to concrete, we over-watered the distilled. HOA not happy with that!! One bottle worked on the area affected. We were impressed. However after Hurricane Milton, it caused a huge stain somehow. Not inexpensive but IT WORKED. We will order again to clean the new stain. Highly recommend.

We use this product to remove rust colored stain from battery acid. We followed directions found online on how to properly apply this product. When we put the stain remover on the stain, we allowed it to dry completely before rinsing it off and it completely removed the stain. I have attached before and after photos.

I’ve tried everything on the market to try and get 24 years of dirt, grime and rust off my stucco. I forgot to take before and after pics of my other stubborn stains on stucco below other windows. These pics are just after one spraying on a lighter stain. All my stains disappeared completely after the second spraying. Works great on stubborn rust stains on my concrete driveway. I am so happy I found F9 Barc on Amazon. I am very happy with the results and this product is well worth the price.

This product did the trick. Car battery leaked acid all over concrete driveway. It was a mess. Looked awful. Tried everything to get the stains out. This is the only thing that worked. It was expensive but well worth the money.

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.

Used this product today. I went from having very large and dark rust and battery acid stains from my golf cart to a very white, clean driveway. I’ve had professionals power wash my house and driveway before and although they did get some of the stains out, they still remained, only faded. I highly recommend this product. WOW just WOW.

This product works! I have tried several products over the years to remove rust stains on my concrete and nothing seemed to work. I saw a YouTube video regarding this product and decided to try it. First pass got rid of 75%. Second pass got rid of 99%.
