Question: Will this work on black-topped driveways as well, or is the surface too porous? If not, any idea what will work? I’ve encountered this on a couple of older driveways which have not been sealed anytime recently.

Garage Oil Spots
One of the most common problems that almost everybody has is oil or grease spots on the concrete driveways and the garage. It is really fairly easy to take care of them even with an older grease spot. Now this is a fresh spot, and the first thing you want to do is to wipe up the excess that is on the surface. And, once you get that done, you start with the magic formula.
You are going to do is take paintthinner and pour the paint thinner on the spot and saturate it real good. The reason you want to do that is to make it liquid. And even though this has got an oily residue, when we put the next step, which is to pour cat litter over it, and than spread that out real good, so that you have got a nice layer over the oil spot. And now, if we just leave that there overnight, when we come back we are going to be able to sweep it up, and the oil spot will be gone. Sometimes you have to do it twice, but usually the first time is all it is gonna make.
All right, we have waited overnight so now lets take a look at it. And it looks pretty dog gone good. It is easy to do, but let me recap. First of all you wipe away any excess that is on the surface, then you saturate the spot with paintthinner and then you can use any kind of an absorbent, we used cat litter, but you can use baking soda, corn meal, dry sand, anything like that. And then after you wait 24 hours and sweep it up, if you still have a spot there, put a little laundry bleach on top of it. That will probably take care of it.
