There are several ink blots on the palm rest of my iBook from holding a leaky pen over it by mistake (obviously). I've tried using rubbing alcohol (70%) on cotton swaves and rubbing it in, didn't work. I've tried letting rubbing alcohol jsut sit on the palmrest, that did not help much. I've tried using iCleaner, that was basically useless. Does anyone know any good ways of getting ink off of the plastic that's in the iBook?
