Best Concrete Cleaner

[Old Henry]

After Old Henry had a major "accident" on the driveway Monday I didn't get to cleaning up his mess until a few days later. By then the black oil had soaked well into the driveway and stained it good. I tried my usual blacktop and concrete cleaner from Ace Hardware that works great on the painted floor of my garage but it hardly touched the stain on my driveway. We have a major social function in G'Raj Mahal tomorrow so I wanted to get that stain off. Ran into Behr brand concrete degreaser and cleaner yesterday at home depot and tried it. It did amazingly well in removing almost all traces of the stain.

Here's what the stain looked like after Old Henry's "accident":



Here's what I first tried:

Here's how the stain looked after the Behr cleaner. I left the stain on the road to show how bad it was on the driveway that we cleaned. The cleaner didn't work as well on the old rougher sidewalk next to the road nor on the asphalt as it did on my smoother driveway.
