Clean Ink (exploded pen) off Magic Mouse?

Hi everyone,

I was transporting my magic mouse in a backpack. Unfortunately, a blue ink ball point pen exploded in my bag, and all the ink seemed to end up on the magic mouse. It is a very dark ink stain, so it seems pretty thick. I tried cleaning it off with just vinegar (just because it was around and not particularly bad/damaging), but that appeasr to have done nothing.

The bulk of the ink is on the top surface of the mouse, with some on the aluminium on the bottom. If anyone has suggestions for either of these surfaces (well, the top in particular), that would be great!
