To prepare the solution for cleaning LCD monitors, you will need deionized or distilled water and vinegar or iso-propyl alcohol [a bottle of vodka should do] – Don’t use tap water or mineral water as they could leave white marks on the screen because of the dissolved salts.

Dilute the vinegar or IPA with distilled water [1:1] and spray this liquid on the cloth. Never ever spray liquid directly onto the LCD screen. Moisten the cloth with this home made LCD cleaner and gently move the wet cloth in just one direction – from top to bottom.
