Hey guys, what do you use to clean your Macbook Pro keys and hand area (where your hands rest when you type, left and right of the trackpad)? I find that area can get "grimey" with white spots on it after some time; I'm guessing from moisture and slight human sweat? Also, how/what do you guys do to clean the trackpad? That too can get a little "sticky" (not sticky in a gross stain from food/drink kind of way, but just from humidity and moisture making it a bit harder to mouse and scroll, etc.)?
