Hi-I had my concrete driveway and inside garage floor epoxy painted and Tucson, AZ heat has taken its toll-leaveing black tire marks -hard to remove and inside-hot tires picked up paint when parked dn to the bare concrete. Can you suggest what can be used to remove same? Contacted companies of steam cleaning and sandblasting which wasn't recommended due to damage of concrete. I have 550 sq ft outsite driveway and 450 sq feet inside garage.
