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.
