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!
