Driveway has orange spots that won't budge

I had the same orange marks in Lehigh. A rust treatment made for concrete cleared most of them; a pressure washer alone didn’t do much. Don’t use a turbo nozzle or hold a high-pressure tip close, because that can leave permanent marks.

Those sprinkler stains are usually iron, and plain water won’t dissolve them. There are rust removers labeled for concrete that can work, but test a small spot first and follow the directions—some products can discolor the surface if left on too long.
