Getting rid of car oil on the driveway

[Kazbah]

I also use sawdust - found this out by accident - just spread it out on the stain and using a stiff broom, broom it in almost like "rubbing" it in.

I recall Dad using good old Dynamo and adding a bit of water and scrubbing with a strong brush (wire or outdoor broom) - massive stains too. Worked a treat!
