Okay, I know this has been a bit over-discussed, but I'm trying to tidy up my trusty iBook (circa early 2005) and I wanted to get rid of the dreaded "wrist-rest" marks below the keyboard, but there's also some smudging on the outer corners of the trackpad. I read a post somewhere on here that warned against using Magic Erasers on the trackpad because it would cause it to stop working?? Is there any truth to this, and if so is there anything else I can use to clean that particular area? Thanks!
