------------------
Dan,
Mundane or not, ghosting on white boards is a real problem most of us face.
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.
