Removing hydraulic fluid from asphalt driveway

I pulverized oil dry (clay) and that removed much of the wetness but it is still stained. I'm heading back up with dish soap and roof brushes to scrub it. Anything else I should try?

Thanks.

My best suggestion for doing it now with stuff easily sourced:
Any residuals on surface can be lifted with brake clean, but you gotta have rags at the ready to quickly soak it up before the solvents evaporate and the oils settle back to the surface. After that, use your dried clay to combine with a dish soap & Easy Off Oven Cleaner to create a poultice of sorts. The sodium hydroxide in the Easy Off will break the oils down into smaller molecules, the dish soap acts as a surfactant to suspend the oils and keep them from seeping back into the concrete, and your dried clay to soak up the naughty bits.

My best suggestion overall:
Get some EBC, (Enviro Bio Cleaner), which is available online and at some Sherwin Williams stores as well. 2-3 applications with adequate dwell time, some agitation from a stiff brush, and a thorough rinse will remove everything which can be removed. Important to understand though that some "shadows" can remain even after the oil is removed from the surface, due to the porosity of concrete.

Having access to a hot water pressure washer is a bonus, but EBC is one of the most effective oil stain removers on the planet when all you have is cold water. Trusted by professional pressure washers around the world and invented by a fellow pressure washer and friend, Carlos Gonzalez.

I’ve had a couple guys soaping/scrubbing/rinsing for a couple hours and we’ve made progress. I have to come back for a little CO next week so I’ll see what it looks like when it’s dry.

I cleaned up a pretty big one today size of a dinner plate. I believe I got it but I will know more later. Can’t tell because the driveway was too wet from water.

Remaining big one is watermelon sized, black mottled area about five inches across in the center and the outside donut area is brown. It’s also the most noticeable. There were smaller orange sized stains but they cleaned up okay.

Actually I’m not even sure the big remaining one is from hydraulic oil. I had a rented hoopdie dump truck parked there for weeks. I think it is diesel engine oil.

Thanks for the suggestions everyone.

There is a small complication to seal coating. The driveway is shared by the neighboring condo owner. Not shared in that they both use the same areas but shared as in contiguous.

Anyway I’ll likely be doing the same job at her house so maybe I can convince everyone it makes sense to wait until I’ve spilled all kinds of stuff on her driveway first before we sealcoat 😂

Welp, stopped by to get the rest of my stuff. Soap and water and scrubbing did nothing for the stains. Just bite the bullet and seal the driveway lol. @Robie go ahead say it!

I will try some clay and soap and maybe something else another day.

I got lucky. Very first day I started working a current job, I jack knifed my bros trailer and bros trailer and broke a whole four quart jug of hydraulic fluid on the clients driveway. I got lucky as it was just a non maintained 3/4 minus driveway. The owner saw right away but I already had a load of base on the way and her driveway became better.

Reggi is there a pic u posted of it?

No, I was gonna take a pic yesterday but it looked bad enough that no pic is necessary. It looks worse now that we have rinsed and swept away all the stone dust and sand that was covering the driveway.

It’s ****ed.
