Can't help myself. Just figured out how to clean LCD displays. Use a dry microfiber cloth. Removes dirt and dust with ease. Also removes oily fingerprints that idiot coworkers love to leave behind after they've poked the hell out of your LCD panel. Make sure your cloth is clean as the trapped particles can scratch sensitive surfaces. I got a pack of eight 12" x 12" cloths for $5 at Kmart in the automotive cleaning section. Target also carries these things. Also good for cleaning trackballs and camera lenses. Works well at removing greasy smudge prints from glasses with a dry cloth.
