What is the best way to clean an LCD monitor?

I recommend a good microfiber with just a little bit of water.

"Use a non abrasive cleaning solution, diluting isopropyl alcohol (not rubbing alcohol, as it may contain oil) into a solution of 50% alcohol and 50% with distilled water water (or purified/bottled water). You could also buy a cleaning solution that does not contain bleach, ammonia, or vinegar.

Before you start, power-off and unplug your monitor. Spray the cleaning solution on a soft cloth (for example an old T-shirt), lint-free microfiber cloth, or some other very soft cloth. A large cloth is best, since it will help reducing the risk of leaving streaks across the display from finger pressure.

Starting from the top, wipe the screen in one direction until you have cleaned the entire screen. Apply light, but distributed pressure. Repeat if necessary. Let it air dry."

I use the cleaning wipes for my glasses. They are much cheaper and you can get them in any supermarket.

"You can buy anti-static screen-wipes designed for the purpose.

As an example, we can get these in the UK: link

I would expect any decent office supply company to sell them"

"A damp cloth.

Most anything like that will do, but:

Be a bit careful with paper towels. Some may contain fragments of wooden fibers, which may be too hard for the surface if you wipe vigorously. Works fine if you only need to gently wipe off the dust.

Don't use too much water (or any liquid) so that it runs down the screen. It can seep through at the edge of the screen and cause rust or a short circuit. If you spray something directly on the screen you will obviously risk running, so spray it on the cloth instead."
