Permanent Marker on Computer Monitor

What do you do when you realize that a Monkeytot has written on your LCD (or other kind of) screen with permanent marker? You ask Artgal. And Artgal promptly tells you to use a dry erase marker to clean it. And it works.

One caution: use Heloise's advice, and wipe into the mark, not out from. If you wipe across your mark, it will smudge the dry erase ink and need more cleaning.
