I'd be very careful with acetone, it tends to dissolve a lot
of things, like maybe the binder in the coating.
Rubbing alcohol (isopropyl) and pure ethanol are the things
I've seen used to clean magnetic media.
if there is a spot that is not actually used (maybe other
parts of the gouged tracks) you could test various solvents
with a Q-tip to make sure they don't cause damage.
