Does anyone have a solution for removing diesel oil stains from concrete?

I tried Auto Zone's driveway cleaner, better, but not gone.

Thanks,

I have not found anything that eliminates the stain, but WD40 will help deminish it.

I was told to use brake fluid to get diesel oil out of carpeting...I haven't tried it on concrete, but it's worth a shot.

I recall reading once that
laundry soap with coca cola
worked to get oil off concrete.
You could try dishwashing soap
and a brush (like oil spill clean ups)
and maybe follow that up with muriatic acid etch.
Be careful with acids and be aware that the
acid leaves the concrete kind of bleached.

Have you tried a jackhammer? It works very well.
