You're talking about an oxford cloth shirt, right? As in, a typical dress shirt? I send my shirts to a cleaner after every wear, and any stains/spots usually come right out. Also, a chemist once told me that vinegar is good for removing certain types of stains (I suppose because of some kind of acid/base reaction, or other chemical magic).
