I have loads of grubby finger marks on my monitor (mine and smaller people's). I'm not sure how to clean them off without damaging the monitor.
What's the best way to safely clean dust, smudges and fingerprints off an LCD?

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.
Apple has a page that describes how to clean your Macbook display. It says
Dampen a clean, soft, lint-free cloth or paper with water only and wipe the screen. Do not spray liquid directly on the screen.
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.
It's expensive, but works very well. Worth every penny!
When I got my first laptop about 8 years ago, we were advised that the easiset thing to clean it with is damp toilet paper, because it's a lot softer than tissues, and more common and cheaper than micro-fibre wipes or glass-cleaning cloths.
I've been doing this for years with no adverse results, however sometimes you get tiny flecks of paper left on the screen (wait for it to dry and just blow them off).
Micro-fiber cloth slightly dampened. I generally wash the micro-fiber clothes I have used to wax my car, and even afterwards some of the wax is stuck within the cloth, with a bit of moisture it helps protect the LCD and gives it a protective layer, from then on removing fingerprints or other such items from the screen has become easier.
I also make sure to make everyone that is about to point at my screen that putting their finger on it is sure to be a fast way for them to lose it :P
