I've had success with dawn and baking soda scrubbed in. Let it soak in for a while, then spray with bleach. Then let it soak some more, then pressure wash.


ETA:

When I did this recently it made the spot too clean and then I had to clean the whole damn garage to match it or my OCD would start going haywire

Pour Johnny Cat on it.
Scrub it in with your shoes or boots. (Great fun for the neighborhood kids).
Sweep it up.

Carb cleaner + rubbing in kitty litter have given me the best results

I've had decent success with torching them out if they are less than a couple years old

Found this: If using dish soap doesn't work, you can try spraying the stain with oven cleaner, WD-40, or a mixture of bleach and water and letting it soak for a few minutes. Then scrub it with a brush or a piece of steel wool and repeat the process until the stain is gone.

I use the aerosol version of this. I spill a ton of oil and grease on the driveway working on my Jeep. I’ve gotten to where I don’t even clean it up anymore until I’m done - sometimes a week later. It works really well.

For the aerosol I spray it, let sit for 5 min, and spray it off with a hose. Every once in a while I’ll use the deck brush to scrub it in if it’s a bad enough stain.
