I have a 2010 MBP and lately I've noticed dust showing up underneath the keys and above under the screen hinge. I've looked at the ifixit.com tutorials here but they don't have any guides on how to clean dust. I also have AppleCare, but this thread mentions it doesn't cover cleaning dust. I imagine "dusty" would be subjective, but they could give you 2 cleans a year or something. Can anyone verify that they don't clean dust from parts? In the end I'll probably open it up and use a dust-buster, but thought it'd be good to check first.
