Preventive Maintenance

Cleaning the Keyboard

You should clean the keyboard periodically to rid it of dust, lint, and any other foreign particles that may become trapped beneath the keys. Use a can of compressed air with a straw extension attached to blow air in and around the keys.

Cleaning the keyboard prevents keys from sticking and jamming. It also makes typing a more pleasant experience.

ÄCAUTION: Do not use liquids of any kind on the keyboard, because they may permanently damage your keyboard.

ÄCAUTION: Do not use a regular vacuum cleaner for cleaning the keyboard because you may deposit normal household debris on the surfaces rather than remove it.

JTip Foam swabs or cosmetic applicators are preferred to cotton swabs because cotton can add rather than remove lint.
