2Absorb the diluted detergent into a sponge.

3Squeeze excess liquid from the sponge.

4Wipe the cover with the sponge, using a circular motion and taking care not to let any excess liquid drip.

5Wipe the surface to remove the detergent.

6Rinse the sponge with clean running water.

7Wipe the cover with the clean sponge.

8Wipe the surface again with a dry, soft lint-free cloth.

9Wait for the surface to dry completely and remove any cloth fibers from the computer surface.
