My solution (no pun intended) is to use good ol' rubbing alcohol. Either the 70% isopropyl or 70% ethyl plus acetone work fine - watch what you use the acetone on, it can cloud plastics. Put a spray pump in the pint bottle, and let your instructors have at it. It smells enough that they won't use a lot, but it will exorcize the ghosts. I hate to admit it, but I have used this to remove dry erase marker from projection screens when instructors don't look and just start writing on whatever may be on the wall behind them - hey, it's white... If you haven't tried it, this also works on most ball point pen inks that are used to draw on lab desktops in idle moments. Regards, Dave PS - The 99% variety is also a great tape head cleaner. I'm such a wealth of cleaning information... - I've been at this too long.
