Removing Magic Marker?

["Warren 'Llama' Ernst" <warren@warrenernst_nospam.com>]

All,

Well, after at least 9 years away from my beloved Apple II, I'm getting 
back in the game. I figure I better hurry if I want to get in on all the 
new hardware people came up with, but won't be making any more.

As such, though I have a souped up //e, I've just acquired half a dozen GS-
es (4 work, 2 are parts only) and a color monitor. Though I worked at 
Beagle Bros for years, I've never owned a GS before.

Anyway, here's the first of what will be many questions:

What's the best way to remove black magic marker writing from a standard 
IIGS case? Any special solvents or products I should use. These things 
aren't totally covered in grafitti, but I wouldn't mind cleaning them up.

Future questions will deal with transferring disk images from a PC, and 
GS/OS in general...

Thanks,
Warr (former Beagle Bros tech support)
