Remove rust stain from concrete
 

Which rust removal products have you had success with? These stains are from a battery hold down bracket and hardware that had been sitting there for less than 2 hours.

I've had very good luck with Iron Out. Right after our house was repainted, we had a feed hose to the hose rack pop a leak (hard water with lots of iron) and this stuff worked great on the paint and exposed foundation.
