Cleaning the cover of your computer
Occasionally clean your computer as follows:

Prepare a mixture of a gentle kitchen-use detergent (one that does not
contain abrasive powder or strong chemicals such as acid or alkaline).
Use 5 parts water to 1 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 cloth fibers
from the computer surface.
Note: Shut down the computer and then disconnect the power cord before cleaning
the computer.
