How to Clean Oil Stains from Cement ?

[ChrisD46]

I tried Dawn dish soap with hot water and a scrub brush but it did nothing to remove oil stains from my cement drive way - your experiences how to best remove ?

I've had good luck with stuff like this:

I've also used this one. They seem to be about the same:

I've seen some folks have success with a weed burner / propane torch, but I wouldn't do it if there's any moisture in the concrete, it could pop a chunk up.

POUR-N-RESTORE works exactly as advertised. Not inexpensive, but it will draw out all of the oil stain and leave your driveway looking like new. Really easy and simple to use too.

Pressure washer sometimes works for me.

I use a citrus cleaner, with a brush to agitate it and work it into the surface keeping it wet. I let it soak for about 30 minutes then power wash it out.

I boil water and dribble it on the stain to heat it up. Get a bunch of water boiled up.
Don't just dump the hot water on the stain as it runs off without departing the heat.
Then I shoot the stain with Purple Power. I'm sure the other modern cleaners -Simple Green/Orange Power- would work too.

Rinse and repeat.
I wet the region around the stain so the "dirty rinse water" doesn't stain any concrete downhill from the original stain.

I do want to try the "Pour N Restore mentioned above.
