I have been using Monster screen cleaner from Best Buy, but it SUCKS. I used to have iKlear but I remember that too was not great. Any tips/ products to actually clean one of these MBP screens and not have streaks and lines left over?
I use iKlear with the micro-fiber cloth that they include. It cleans the laptop and screen very well, and removed smudges and grease that water just can't take off.
Water has always worked best.
I should sell some in a bottle, labeled Mac Clear and charge 20 bucks for it.
