How should I clean a matte display screen? I have an HP x20LED monitor that has a lot of dust accumulated and a fair amount of smudges. How should I clean the dust off and buff out the smudges? The instruction booklet says to wipe the chassis with a clean cloth dampened with water and to clean the screen with an antistatic screen cleaner that doesn't contain benzene, thinner, ammonia, or any other volatile substances.
But the instructions are quite lacking because it doesn't specify which kind of cloth to use and how to clean the screen other than to use an antistatic screen cleaner. I tried the nice'n clean electronic cleaning wipes once before, but I think they're the source of some of the smudges. So, I don't want to use them again, and I'm not sure which other cleaners are safe to use.
