It’s about 3 days old. I can’t get to Home Depot for awhile for whatever they have. I don’t trust random methods on YouTube.

oven cleaner, the good stuff. It's essentially lye, which turns oils/fats into soap.

But you put it on asphalt, it will eat it.

I've had some success with dawn dish soap and a good scrub, assuming you've blotted up all the standing liquid. Might be worth a try before you reach for something stronger. Dawn won't have any chance of harming the surface.

Dish washer stuff works.

I'd soak up the top layer with sawdust or cat litter, then liberal application of dish soap, let sit and then scrub with stiff brush. Repeat.

Oven cleaner sounds easier.

Go buy the cheapest Kitty Litre you can find.... Open package a sprinkle on top of stain.

Put on you oldest pair of Tennis Shoes, use the bottom of shoes to scratch the kitty litter into the surface. Get all of the spots of oil, and sweep up powdery mess, and you are done.

It can matter a little what the finish is. For a very smooth surface, alternate between a solvent like paint thinner (or solvent based concrete cleaner) and dish soap and/or baking soda in expanding areas.

For slightly rough to brushed surfaces, clay based kitty litter/oil absorbent and dish soap and massage rotating on the ball of the foot or hard force on an orbital sander/polisher.

I'll second Microman...
Diatomaceous earth (kitty litter) to soak up every last bit.
Also used in machine shops to clean oil and oil-based coolant spills... called "Floor-Dry" in the college shop.

If anything remains soaked into the concrete, I'd use a dishwasher detergent powder sprinkled on, and then slightly dampened... let soak a few hours, then use kitty litter to soak up and sweep up.

Dawn dish soap does the trick. Leave it soak for a week or two.

I'll cast another vote for the Microman method. We'd use that at the gas station where I worked for fresh spills, occasionally following up afterwards with a product called "Crete Sweep" that I suspect was nothing more than portland cement powder in a shaker can.
