Regular household cleaners may damage a monitor screen, wearing away coatings.
Instead, gently wipe your screen with a soft cloth. A microfiber cloth is great for this purpose.

You can dampen your cloth with distilled or filtered water to wipe away tougher smudges. Plain water usually works, too, but filtered or distilled water will help you avoid streaks.

If heavier cleaning is needed, moisten a cloth with a 50-50 mix of distilled water and distilled white vinegar and gently rub your screen clean.
