Cleaning Oil Stains Out Of A Brick Driveway? Any Hints?

I have a proper industrial high pressure petrol powered pressure, gav it a blast with that last night, to no avail.
So any ideas? Other than replacing the stained bricks?

I tried the coke meathod and it didn't work all too well, but better than water.
Petrol actually worked very well, but it is very dangerous as you can imagine.
One thing I found best, was after all the scrubbing pressure washing etc I used a wire brush and it seemed to take all the top layer of concrete away leaving a clean surface.

For oil stains, Gunk is fine. If you have no Gunk, make your own. Make a 50/50 mix of liquid laundry deteregent and kerosene (diesel, or mineral spirits). Stir the mix until it turns "white" then spread it heavily over the oil stains. Allow it to soak in for an hour or so working it periodically with a stiff broom/brush. Then wash it off. The pressure washer will be great here. A second treatment (or more) will be needed if the stain is old and deep.
For brake fluid, simply wet the surface with water and work some liquid laundry detergent into the stain. Allow it to soak for a while then wash off. (Excluding DOT-5 fluid).
For rust stains, the "Coke" method may work. You are relying on the Coke's phosphoric acid to do the work. I have better luck with real phosphoric acid (used for rust removal and paint preparation) diluted and sprayed on with a pump type garden sprayer. Wet the surface with water, spray on the acid (or Coke), brush it in and allow it a short while to work, then rinse with water.
Lastly, for extreme stains use Muriatic acid. I don't know what they call it in the U.K. but Muriatic acid is a partially dilute version of Hydrochloric acid used for commercial cleaning purposes. It is available in the paint section of most DIY stores. WEAR GLOVES, EYE PROTECTION and apply it sparingly to a surface you have already sprayed water on. Brush it in then hose it off.
