    One way I've heard is to pour some cola (pop) on it, let it soak a while, then scrub with a brush and rinse. I don't know how well this works, but it's easy enough that it's worth a try.

    Friends of mine own a garage and at the end of the work day they pour "purple power" over the stains and let them sit for about 30 min then scrub with a push broom and then rinse. They tell me it works well.

    If you don't mind taking some precautions, then use TSP (trisodium phosphate), it WILL do the job. Here is an article from The Family Handyman showing how. https://www.familyhandyman.com/garage/removing-oil-paint-and-other-concrete-stains/view-all/ ;

    Baking soda on it, then our white vinegar. It will fizz like a science experiment. Will not hurt it. Dawn dishwashing liquid may help. If nothing works, try lightly sanding it with some sand paper. The sand paper worked for me on a brick patio. Use rough grain.

    If nothing absolutely will work - muriatic acid (which is hydrochloric acid) at a 10% dilution. 10 parts water, then add to it one part acid in a sturdy 5 gallon bucket. No SPLASHING. But you must wear safety glasses, old clothing, special gloves. Read up on it prior to using it as it is VERY dangerous. No children around etc....

    I would try covering the area with kitty litter and let it sit and absorb. Then sweep up.

    For small areas, you can liberally sprinkle corn starch on the spots (the concrete must be dry). Let sit for a couple of hours and then brush away. Most of the grease/oil should have been absorbed by the cornstarch. You can then scrub with dish soap and rinse.

    I found the cornstarch works better than kitty litter on textured concrete because the particles are smaller and they can actually get down into the course texture of the concrete. Kitty litter does work very well on a smooth concrete surface though.

    You can use Tide washing liquid. Wet the spot put the Tide on it and scrub with a broom then rinse with water. I used to work in a service station and that is how we cleaned the grease spots on the concrete.
