The best way to clean your computer monitor is to use a very soft microfiber cloth, and wipe the screen down very gently. You can dampen (don’t soak) the cloth with distilled water, or 50% distilled water and 50% vinegar if you need to. Also, it’s a good idea to turn the screen off when cleaning it. As I’m sure you’re already aware, this will allow you to see every little speck of dust! This is usually a very annoying thing, but when cleaning, it’s great!
