Ok this may sound crazy but I use my hoover.

I've got a Vax 6131

I use the duster attachment, actually bought a spare one that is only used on my screen, nothing else and hoover my screen with that.

Afterwards I go over it with a screen cleaner, basically screen wipes I buy for a couple quid from a website called SVP, it's UK based though but obviously the same stuff can be bought in the US.

Some people may frown on the hoover idea but I've been doing it 4 years on 3 screens and never had any problems.
