I use just a clean handkerchief or a dry dust cloth or so to wipe off the dusk. Nothing special. No chemicals.
What does everyone use for cleaning their LCD screen? I bought Monster ScreenClean and a cleaning cloth made by Monster that looks like terry cloth.
I cleaned it for the first time after having it for 6 months when I noticed a lot of dust when it was turned off, and the sun coming in through the window hit the screen just so.
After cleaning it, when the sun hits it now, I can see what looks like a hazy film over the screen like it didn't clean properly. You can see the circular motions of the cleaning cloth. I didn't use excessive pressure.
When the TV is on, I don't see it.
