During everyday use, a keyboard can get pretty dirty and sticky
Dirt and other debris can fall or accumulate between the keys and cause damage or prevent the keys from functioning properly
To clean your computer's keyboard you must use either canned air/gas or a small computer-specific vacuum cleaner
NEVER apply any cleaner or liquid directly to your keyboard
If the keys are dirty, use a lint-free cloth that has been sprayed with computer cleaner to lightly and carefully clean your computer's keyboard
DO NOT clean your computer while the computer is operating, and avoid using your computer till the cleaner has dissipated to avoid possible damage to your equipment
