Cleaning rust off concrete?

[JimVonBaden]

So, like a *****, I was grinding a lot of metal on my driveway and it left a lot of metal dust on it. I didn't sweep it off before it rained and the concrete now has a nice rusty patina that my wife is not happy about. I tried power washing, but that didn't touch it. Is there a chemical I can use?

Thanks,

Jim

Use Iron Out

Be careful using CLR.... it will leave spots on your concrete if you don't wash it off ASAP!

Try Krud Kutter Red Clay Stain Remover. It works great for removing red clay stains off of concrete.

Edgewater industries makes a rust stain remover http://www.pour-n-restore.com/CA-Rust-Remover-Flyer.pdf

I have never sold it and do not have any. I could contact my rep and see about getting a sample.

Sounds like an interesting idea!

PS CLR didn't touch it, and yes, I rinsed it off thoroughly!

I know of someone who actually used that product and was happy with the results. I think the key was to attack it sooner than later for it to be most effective, but I'm not sure. I would definitely try it.
