rust stains on concrete

What is the BEST product to use to get out rust stains on the driveway? I hired some guys to cut down a manhole cover that stuck up 4"above grade. While grinding it down, the iron dust created, landed on the driveway and stained it. I thought it would just wash away but it soaked in after a rain and now I can't get it out. Thanks for any help.

You may want to look at this product.
Ferrous Stain Remover.
It is a SureKlean product.

If the stains are light and not too old, scrub them off with concentrated laundry detergent (like Fab) and a steel brush. Add water as you go.

It won't be easy or fast, but you have to be patient - it works.

The lesson here is very clear: When you hire sub contractors or handymen, you got to let them know that they can't do their job and mess up something else. Hold them responsible for damages they cause. An easy way to do it is by holding a "retainer" - part of the payment, to make sure they finish their job cleanly and without destroying something else.

Took my rust marks about a year and half before they disappeared on their own, with no treatment.

Caused when I broadcasted Ironite fertilizer, trying hard to keep it only on the grass, but found out later that a few pebbles landed on the sidewalk and driveway. Each little pebble left a long, downhill rust streak when it rained later that week.

Dissolve oxalic acid crystals in hot water, scrub with a nylon or natural bristle brush.

Thanks dj1, I am 64 and do tons of stuff on my own but cutting down the manhole cover was out of my league. Lesson learned I guess. I'll call the owner of the company and let him know that I need help in fixing this mess.

What he said. Oxalic acid is the main ingredient in any packaged 'rust stain remover'.
