This will remove all of the oil from the surface, but if the pavement is particularly porous, and a light stain remains, you may use a carpet cleaning machine with water and TKO instead of shampoo to remove the remaining stain. The carpet cleaner forces the TKO into the pores and sucks it back out, along with the oil.
