Hey all, I'm sure most everyone has the apple keyboards with clear plastic and white keys. I've had my iMac for about a year now, and the keyboard is showing a good amount of dirt on the inside of it. Is there a way to take it apart and clean it? I have the Bluetooth wireless keyboard ... all I see on the back, besides the battery door, are two tiny little screws that look like they would come undone with a small allen wrench. Are those what I'm supposed to remove?
