And don't spray directly on the screen, spray it on the shirt/sock/cloth.

If your looking for the best solution, get a good micro-fiber cloth, such as one by Cobra. http://www.autogeek.net/cobra-deluxe...ber-towel.html or this one (yes it's better) http://www.autogeek.net/ww1627.html

Don't waste money on LCD screen cleaning kits that give you 1oz of Windex which costs 11 cents and a $3.00 cloth for $30.00 or more.

It's true strait Ammonia and Ammonia based products are bad for tinted windows, but not necessarily true for plastics i.e. Plexiglass. The alternative is Alcohol, which can be just as bad, if not worse on some plastics. Windex is perfectly safe and is excellent at removing oils and leaving streak-free. much better then alcohol based cleaners.
