or your porus driveway - take your "oil dri" stuff - sprinkle on, let sit AT LEAST 1 hour, THEN take some old shoes and grind that oil dri into concrete (or whatever it is) let sit a couple more hours - every so often spreading around and grinding it in some more. (to many folks just pour it on & sweep it up) Grind it in until it's like powder, add more if you need to - We've all done the same S$%^ as far as oil spills - so it's not a "mental failure" on your part. It could be worse, you could've have forgotten to put plug back in and dumped new oil through motor onto driveway
