How to clean old engine oil stain from concrete garage floor?

[MissLaurus]

Can anyone suggest the best way to remove an old, pretty large oil stain from the garage floor in my home? Practical advice would be much appreciated!

I have never found a way to 100% clean motor oil out of concrete.



I have tried soaps that break down oil but there is always some stain left behind.



Try a strong pine-sol mixture and soak, scrub and pressure wash. Dawn cuts oil good also.



Others may have a cure.

Let us know your results.

What Bud says, you might have some good luck with a pressure washer surface cleaner. These can be rented. Link to show what I'm talking about. They have the advantage of containing the water better than just a straight wand. Straight up Simple Green does a pretty good job at breaking down oil as well.
