Rust Remover for Concrete (Case of 3 makes 3 gallons)

We had rust stains on the concrete from garden pots and we tried several chemical and non chemical solutions and high pressure hosing to remove the stains. Nothing worked. This product removed all stains first try. It's just magic. Finally a product that does what it claims to do. Thank you!!

I had rust spots on my concrete fro lawn fertilizer. This product was excellent and i highly recommend it for rust removal. Followed the directions and with very little effort I had all stains completely ( not slightly), removed in 30 min You can't tell where any stains were and the product did not discolor the concrete. Very happy

Thank You

At first it is good, but after several days, the rusty color coming back.

I’ve tried several products from other manufacturers but this one works the best for vertical and horizontal concrete surfaces. Our basement floor and foundation had some tough iron stains from our well water system. Get a 5 gallon bucket and a few containers of this powder. Mix a few gallons of water and start mopping it. Keep applying and keep mopping. A tough scrub brush works for tough spots. Warning it turns into a gel and is very slippery when wet. Use some ice fishing cleats to keep from slipping. There’s some foul odors so have some ventilation fans going. P.S. iron out works great for tubs, sinks and toilets.
