How can I remove car oil off my drive way

Did you try cat litter to absorb the oil and then straight bleach

Cat litter to absorb then scrub with Dawn dish soap.

Blue dawn dish soap or a purple degreaser

Have you tried Dawn dish liquid and water? I have had success with it and remember, they use this mixture to clean animals after an oil spill! Much success. If this does not work, try baking soda and vinegar to lift it from the cracks of the concrete and eventually lift it all out.

Peat moss absorbs oil more effectively than kitty liter. Some brands are Sphag Sorb and New Pig

Wet your driveway then use a paste of baking soda and blue Dawn dish soap. Use a stiff scrub brush and go to work. It should remove it.

Both Dawn & combine with kitty litter worked for us.
