Blowing air into the small holes in the back under the door sometimes works, but other times not so much. I know it has worked for me on more than one occasion, but then refused to work on other attempts. These differing results likely were on different machines, so it's hard to generalize, but the good news is it can't hurt to try it. Use canned air for electronics which is certain to be quite dry, and not from an industrial compressor, which can contain oils and/or moisture.

Also, one time after failing with the air, I was able to remove a spec of dust stuck under the cover glass by tapping the covering widow sharply with an eraser. To my surprise, this worked. But the dust is still in there, and could be back at any time. Obviously don't hit too hard, as the cover can and will break; I think the key is sharpness of the hit, not strength. Maybe try to drop the eraser (or other small/soft object) onto the screen.
