Please help! My diesel truck leaked oil on the driveway of my new
house. The driveway has stones mixed in with concrete on the surface
and it's been sealed.

I took some paper towels right away to it to blot out the leak, but
the discoloration is still there. I'm told I can hire someone to try
to get that out, but I thought I'd try to clean it myself first.

Can someone please recommend some cleaning solutions I can try on it?
I've been told Spray Nine and even some brake cleaner with newspaper.
Is there a surefire method of getting something like out on a driveway
like this? TIA!
