Appendix B. Use and care information
 Cleaning your computer keyboard
1 Absorb some isopropyl rubbing alcohol on a soft, dust-free cloth.
2 Wipe each keytop surface with the cloth. Wipe the keys one by one; if
you wipe several keys at a time, the cloth may hook onto an adjacent
key and possibly damage it. Make sure that no liquid drips onto or
between the keys.
3 Allow to dry.
4 To remove any crumbs and dust from beneath the keys, you can use a
camera blower with a brush or cool air from a hair drier.
Note: Avoid spraying cleaner directly on the display or the keyboard.
