Cleaning 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 scratch-like 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.
