Cleaning the cover of your computer

Occasionally clean your computer by doing the following:
1. Prepare a mixture of a gentle kitchen-use detergent. The detergent must not contain abrasive powder or
strong chemicals such as acid or alkaline. Use five parts water to one part detergent.
2. Absorb the diluted detergent into a sponge.
3. Squeeze excess liquid from the sponge.
4. Wipe the cover with the sponge, using a circular motion and taking care not to let any excess liquid drip.
5. Wipe the surface to remove the detergent.
6. Rinse the sponge with clean running water.
7. Wipe the cover with the clean sponge.
8. Wipe the surface again with a dry, soft, lint-free cloth.
9. Wait for the surface to dry completely and remove any fibers from the cloth.
Cleaning your computer keyboard
To clean the computer keyboard, do the following:
1. Apply some isopropyl rubbing alcohol to a soft, dust-free cloth.
Note: Avoid spraying cleaner directly onto the keyboard.
2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time,
the cloth might hook onto an adjacent key and possibly damage it. Make sure that no liquid drips onto
or between the keys.
3. Allow to dry.
