To clean your computer

You can clean the computer with a soft cloth dampened with clean water or with
water containing a mild detergent. Do not use an excessively wet cloth, and take care
to keep water out of the case.
Do not use abrasive cleaners, especially on the display. Do not apply any cleaner
directly to the display. Instead, apply the cleaner to a soft cloth and then gently wipe
the display.
You can clean the keyboard with a vacuum cleaner to remove accumulated dust.
