Prepare a small mixture of a gentle kitchen-use detergent (one that does not contain abrasive powder or strong chemicals such as an acid or alkaline). Use 5 parts water to 1 part detergent. 2. Absorb the diluted detergent into a sponge or lint-free, soft cloth. 3. Squeeze out the excess liquid from the sponge or cloth. 4. Wipe the cover, 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 or cloth with clean running water and squeeze out any excess liquid. 7. Wipe the cover with the clean sponge or lint-free, soft cloth. 8. Wipe the surface again with a dry, lint-free, soft cloth. 9. Wait for the surface to dry completely and then remove any fibers left from the sponge or cloth.
