I've been down this road before.
If the guitar has a gloss finish it's not a problem. Get one of those erasers that are used to erase a dry-erase marker board. These erasers work well, you just have to give it a bit more effort than you would for a dry erase marker. I had an entire band sign one of my guitars with a permanent marker and decided to remove the signatures in order to sell the guitar a few years later. The dry-erase marker worked perfectly and didn't leave any marks or scratches at all in the finish.
