Try muratic acid. Just be careful not to leave it on too long or it will eat the concrete surface.

If your driveway is concrete, the best way to remove and clean
old motor oil off your driveway is to spread lots of sawdust
which is cheap and readily absorbs the oil off the driveway.
After that, you take a large broom and sweep off the used
sawdust.
In this way, the driveway is much cleaner, although you cannot
literally remove the oil 100%.

Frankie P is correct. You will not be able to get it completely stain free. Also, I tried the acid approach and that just changed the color of the stain to some kind of orange. I even had a concrete guy look at it and he said it would have to be power sanded to remove the layers damaged by the oil - in other words, you just may be stuck with it. But check this out, if you come up with a product that works, you can probably make a ton of money.

i work at a truck stop and they use floor dry (kitty litter)and a hard brissel broom after it was cleaned up they power wash the bays and parking stalls. however if u dont have access to a power washer u can just use a 2 by 4 or a piece of cardboard and work the kitty litter into the driveway then sweep it up.

no kitty litter will work on a dry oil spot. A strong acid like sulfuric might but you might need a pressure washer strong enough to etch the top layer of concrete (3000psi) or even a protable media blaster (soda or sand). All can be rented or bought at the local home depot.

You will not be able to completely clean the spot no matter what you do. There are solvents you can purchase at hardware and auto parts stores but they can be dangerous and not at all good for your grass when you rinse. A good grease-cutting dishwashing soap like Dawn, and a good brush match with a decent amount of elbow grease will do.

Pour coke a cola on it, let it sit for a while then rinse it off with the garden hose. It worked like a charm for me. Good luck!

I used to put sand on it to absorb the bulk of it sweep it off with a stiff broom then scrub it with strong detergent. You wont shift it all but you should get most of it.

autozone product called Purple Power worked for me after i did an engine swap in the driveway.

a strong degreaser and power washing will do the best job, someone mentioned purple power, its great stuff, and eco-friendly also
