I've been taught "like dissolves like." Althought this doesn't mean to wipe it down with tar, or that there aren't other/better solutions, I'd first start with an oil-based product like 30wt, WD40, 3-in-1, etc. (I was less than impressed with Bug & Tar remover for removing love bugs. WD40 worked better in my situation.)
Mr. Clean Magic Eraser- I never thought of that! It work well?
