liquids directly to the surface.
Clean the keyboard: Wipe the keys one by one with a lint-free cloth dampened in mild soap and water. If
you wipe several keys at a time, the cloth might hook onto an adjacent key and possibly damage it. Avoid
spraying cleaner directly onto the keyboard. To remove any crumbs or dust from beneath the keys, you can
use a camera blower with a brush or use cool air from a hair dryer.
Clean the computer screen: Scratches, oil, dust, chemicals, and ultraviolet light can affect the performance
of your computer screen. Use a dry, soft lint-free cloth to wipe the screen gently. If you see a scratchlike
mark on your screen, it might be a stain. Wipe or dust the stain gently with a soft, dry cloth. If the stain
remains, moisten a soft, lint-free cloth with water or eyeglass cleaner, but do not apply liquids directly to your
computer screen. Ensure that the computer screen is dry before closing it.
