Ack!! Mr. Clean Magic Eraser is far safer, and probably works a lot better.

My friend had his iBook cleaned in 30 seconds, no chemicals at all. Try it.
 
iDuck, the magic eraser has been mentioned MANY MANY times, and while it works on the iBook, it does not work on the MacBook.
 
This is s temporary solution - I guarantee these stains will come back. Even acetone-free nail polish has harsh solvents in it.
