Have you tried liquid laundry detergent?

Cat litter on it for a few days, sweep off, then use Dawn.

+1... Laundry detergent soak and power washing.

Add to those above, bleach for the stain if it remains afterward.

I have found that even a layer of sand can work wonders for the initial cleanup....

Bleach is pretty ineffective for oil stains, the chromophores that cause the color are protected from the bleach via the hydrocarbon oil. A strong surfactant such as trisodium phosphate is best to encapsulate the oil as much as possible so it can be flushed away. The rest will evaporate over time and the stain will fade.

It seems the oil has been removed, only the stain remains. That's how I read it.

'purple power' let it soak in,keep it wet for awhile and then spray it off or power wash carefully. Works great.

Dawn takes grease...out of your way!

Alternate days spraying with aerosol brake cleaner and then long soaks with a degreaser and pressure washing.

Lots of ideas some will work better than others. Anyone with before and after pics that would be useful.

Brake cleaner and oil dry

Why use aerosol brake cleaner instead of regular acetone?

This thread has my interest. I have an oil spill that is like the op's. I want to stain my floor using a solvent H&C stain recommended my demarpaint. I want to clean the oil so there will be no adhesion problems. The oil was spilled several years ago.

What would be the best plan of attack for this. I do plan to use a bit of muriatic acid after i clean the concrete.
