I don't remember where the post was, but I had read that to "erase" permanent markers from page protectors, you could use rubbing alcohol. Someone then commented that using a pencil eraser was even easy. I HAVE FOUND SOMETHING EVEN EASIER!!! NAIL POLISH REMOVER. Works GREAT! And no rubbing! Just a little swipe and the mark is permanently gone. Just had to share this.

That's great. Try hairspray, that works well too and no spilling! Baby wipes work too.
