cleaning lcd's

so i let my younger sister and her friends watch a movie on my pc and now i have some nice perfect fingerprints and some orange stuff im thinking is Cheetos . needless to say she wont be borrowing it anytime soon whats the best way to get fingerprints and other grease marks of an lcd? because a damp soft cloth just spreads it around

You want to use something without any chemicals in it like ammonia or bleach. I use a natural orange cleaner and a microfiber cloth on mine and it works wonders.

well the only cleaners i have are Windex with ammonia and rubbing alcohol 70% and 90%. would 90% rubbing alcohol be ok? im kind of nervous about scratching it or getting chemical stains :/ this is the first time I have ever had greasy fingerprints on it like this
