rust stains

What do ya'll use to remove rust stains from concrete. I did a driveway with my new whirlaway, which worked great except for a few red stains which look like rust. I tried chlorine, but no luck. Thanks, Scott Y.

Like Dave said, oxalic for rust stains........if it's battery acid stains, doesn't work too well

what works for battery acid stains. i had a drive that had battery acid and the owner tried muratic acid and it di nothing. i do not know how he tried to use it because i was not there. i told him i could not get it out abd he went this rout.

F9 BARC works well for orange battery acid stains. This concrete rust remover works great for fertilizer stains on concrete and other types of concrete rust too. This post was from a while ago.. are you still having these types of issues?
