remove fresh rust stains from driveway and sidewalk?

[jake00]

My neighbor rented a dumpster last week. we got a LOT of rain (5")
these are some stains that were left behind. Anyone have any great removal methods?

Oxalic acid,(wood bleach)

Try vinegar.

CLR works really good. Just flush the area really well with water when done. I had bad stains from water getting under my garage door and wetting the steel dust under my belt sander. CLR took it right off. Home Depot sells a generic version in gallon jugs.

Apple cider vinegar works well on rust.

Be mindful of any possible restrictions on run off.

just a wild *** thought but what about putting paper towels down on the concrete and then saturating it with Evaporust, cover with a plastic sheet and let it sit for a few hours. then just rinse away with a hose. It's environmentally safe so should not hurt your grass.

Another thing is iron-x it's a car detailing product that will remove it for sure. But it stinks like nothing else.
