I've used a propane torch and a stiff brass-bristle wire brush. I
melt the paint then immediately brush it off. It will leave black
metallic/carbon marks but the carbon will come off with a scrubbing
using a good concrete cleaning solution and an acid brush once you are
done torching. Then after a year it should all be invisible. With
this method at least nothing petroleum based is "soaking into" the
concrete causing even worse problems.
