It's possible and inexpensive. all you have to do is clean it with paris hilton perfume. The stuff smells like sweat but it really cleans it and afterwards it smell like a new louis vuitton purse.
Try spraying some hair spray on it. Then rinse with cold water. If still there repeat process. Also, my favorite laundry spot remover is ZOUT. It is about $3.00 for a smallish bottle, so I save it for the worst stains, but with ink I still go with hairspray first. If you are not worried about a tiny bit of fading, you can also try denatured alchohol, available at the pharmacy counter in most drug stores. Good luck! (Also, look on Sharpie's web-site. They may have tips as well.)
