First of all, please be patient while awaiting a reply. Secondly, all you have stated was that there’s a “stain”. We don’t have a clue to what kind of stain it is for obvious reasons. Typically, you can wipe the area with a damp cloth to see if it removes the “stain”. If not, try using a mild soap and water. If you’re afraid to do that, take it to a nearby Apple Store and have them take a look at it and see if there’s anything they can do to get the “stain” removed.
