Oily residue on concrete driveway
Q. The falling leaves have been left too long on my driveway and have left an oily residue on the concrete. What do I have to do to get rid of this?
A. Next spring or summer, mix one cup of TSP-PF in a gallon of hot water and scrub the concrete with it using a stiff bristle brush on a long handle to spare your back. Once you are satisfied that the oily residue is gone, rinse the driveway with your garden hose.by
