Cleaning an LCD....again

[Cronos Impera]

Hellow fellow Orgers again.
I have a Samsung SyncMaster940b LCD monitor. Over a week ago when I got back from an expedition I found a ball-pen trace on my monitor. It's small but it can still be disturbing.
I have tried to clean it with a moist cloth but it hasn't worked. Are there chemicals which can deal with it.
Regards,

Common rubbing (Isopropyl) alcohol is your best bet from any grocery or pharmacy store. In fact that is what most commercial cleaners are made of. They just re-package it and charge 10 times as much.

Put some in some sort of spray bottle, but it is best to spray your cleaning cloth rather than directly on the LCD screen

It is also very good for cleaning ball point ink stains from clothing.

Cheers
