Gray film on brick after scrubbing with wire brush -- How do I get rid of it???

I just got done cleaning some spilled paint off of the exterior brick & mortar steps on my house, as well as the brick floor in the foyer (semi-interior). I used some isopropyl alcohol and a wire brush drill attachment. Well, the paint is gone, but now there is a grayish film on the brick. The paint was white, so I'm not sure what's making the gray color. I tried wiping it off with some more alcohol and a rag, but it's not coming off completely. I'm hoping the friction didn't scorch the brick.

Any ideas how I can clean this up? Am I going to have to acid wash it?

Isopropyl alcohol is the wrong kind of alcohol for removing dried latex paint, you should have used denatured alcohol. The wire brush probably did most of the removal and the gray is likely from the steel bristles. I'd try scrubbing with some detergent and see what that does.
