Tire Marks

When hot tires from a recently driven car come in contact with certain types of concrete driveway sealers, the plasticizers from the tire may migrate into and discolor the sealer. To get rid of the discoloration, try cleaning the surface with a concrete degreaser and a stiff brush. If the discoloration has migrated into the sealer, you may need to apply a solvent or totally remove the sealer with a chemical stripper.
