a problem with ghosted marks on your white boards? Mr. Clean Magic
Erasers can work magic. They're all the rage at our local public
schools for getting rid of stubborn marks. Reader Adam French adds:
struggled with this all the time until a friend handed me a Mr. Clean
Magic Eraser. With a little water, it eliminates all ghosting on my old
dry erase board. I generally follow it up with some window cleaner just
to bring back the board's friendly sheen.
