stained cement

Changed my furnace recently, and there was some "metal dust" on the floor, swept it up, threw it out in the trash, but I must have leaked and stained my front cement walkway. Any suggestions to get this off? CLR, Acetone?

Power washer with a concrete cleaner solution.

You could try a stiff bristle brush and a bucket of hot water with "tide" and scrub.

I have had some luck with using vinegar, let is set for 15 or 20 minutes first, if you have TSP try that also, or a light acid wash.
