<human>:  What's the best way to clean a computer keyboard?
<bot>: The best way to clean a computer keyboard is to first turn off the computer, then use a can of compressed air to blow away any dust or debris. Then use a lint-free cloth dampened with a mild soap and warm water to wipe away any smudges or dirt. Finally, once the keyboard is dry, use a keyboard cleaner, such as a rubbing alcohol solution, to remove any residual dust or dirt.
