(Safely) Removing rust from concrete: How?

[69427]

Hey guys,
I have several areas of rusty stain on my driveway from all the grinding dust I've created. Any safe, non-acidic ways to dissolve it?

thanks,
Mike

Hydrochloric Acid is about the most potent you can use. Vinegar may work also, same for citric acid.

i used the pressure washer and it did a pretty good job.....now i use a push broom and sweep it all away.....right after grinding
