Tom, and everyone

Yes, MEK is marvelous and toxic solvent. One should probably include
as part of the "last resort" category. However, it is more viscous
than acetone and applying it carefully dabbing with a Kimwipe should
be okay. Just never ever soak and that applies to just about every
solvent discussed.

Barbara's point about the surface coating is very wise; however, it
might be tough to see whether there is damage to the coating until
the gunk is removed.
