A cool, dark screen helps you see dirt and smudges.
Some good examples of non-abrasive cloths include microfiber, a cotton handkerchief and a T-shirt. Gently wipe the monitor with the soft cloth.
Fill the squirt bottle with equal parts vinegar and distilled water. Close the top and shake to mix.
Spray the cleaner onto your non-abrasive cloth, not the screen itself. Spraying on the screen can cause malfunctions and damage.
With the solution on the rag, lightly wipe the monitor. Let the screen air-dry.
