How do you remove deep black oil spots from a concrete driveway parking pad?

My old car leaked transmission fluid and engine oil onto my clean concrete driveway, creating an ugly dark stain. What household detergents lift oil?

Cover the wet oil stain with a thick layer of clay-based cat litter to absorb liquid. Sweep it up, pour highly concentrated liquid dish soap over the spot, scrub with a stiff brush, and flush.
