(Safely) Removing rust from concrete: How?

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

Check with Lowes Depot....they got it in the paint depts.....I forget the chemical name, damnit....

it's cheeep, or WAS....ain't nuttin cheeeep these daze....

:bonkers:

I have used wood bleach. Oxalylic acid.
