I normally splash some petrol on it, brush it in with a broom and then use the a highpressure cleaner to blast it off.
Works a treat, I used to work as a spray-on-paver and that's how we got rid of oilstains.
But on the hosing part, don't get caught by the water nazis though. I'm guessing about 3:00 AM might be a good time to do it. :s6:
