Whats the best way to clean an lcd tv screen?

with a lint free cloth and breath sure fire make sure set is well cooled sprays and such smear

First try gently wiping it with a slightly damp soft rag, then dry with another soft rag. If greasy streaks are left behind, make a very dilute solution of Dawn, Palmolive, or another dish detergent and wipe with this, followed by a rinse with a wet rag, and then drying with a soft rag. Do not use Windex, Chlorox Cleanup, or other harsh cleaners.

with a lint free cloth

Use a product that's alcohol and solvent free, with anti-static protection preferably. Not sure on the product but i imagine a spray of some description with a micro-fibre cloth to buff the spray off with.

wet a soft cloth,and wring it out as much as possible.GENTLY rub it on the screen until the smudges are gone. Dry with another soft cloth.I have a cleaning business,and I do this to my customers screens all the time with no ill effects.
