I brought a small bottle of LCD cleaner & its amazing, leaves no streaks or anything behind. But i go through it like water & its a bit pricey. I generally read the 2 main ways are: Distilled water mixed with white Vinegar. & Distilled water mixed with 70% Rubbing alcohol, some say 50% But i read rubbing alcohol has lubricants in it that will smudge the screen. So i prob should look for pure isopropyl alcohol. Any suggestions? Do you think the second method is ok? I'm pretty fussy with my LCD's.
