Use Water Only

                    Turn off the computer or display.
- 
                    Lightly dampen a clean soft, lint-free cloth with water only (the soft microfiber cloths work well). Wring the cloth well so no water drips on the keyboard. * Do not spray liquid directly on the screen.
- 
                    Wipe the screen with the damp cloth.
- 
                    Dry the screen with a separate DRY, clean, soft, lint-free cloth.
