I have a cement driveway and its stained black by tree sap and pollen. Does anybody know of a chemical I can use to clean it? I have tried bleech. I even tried a pressure washer.

Bigger pressure washer
99 Silver Z28 A4, T tops, ZR-1 wheels (SOLD) -
Autozone sells driveway cleaner. That combined with a high power pressure washer should work.
