Electrostatic Cleaning Cloths

• For external keyboard dust removal, employ an electrostatic cleaning cloth. Use a cloth of this type to wipe down the outside of the keyboard, providing an easy way to give it a quick weekly clean. If you dust your keyboard as part of your regular cleaning routine, you may not need to follow up with more harsh cleaning methods.
  
  

Compressed Air

• The best cleaning chemical to use for the removal of under-key dirt is not a chemical at all; it's compressed air. Buy a container of compressed air and keep it on hand for whenever your keyboard starts to collect dust. By attaching a thin, straw-like extender, you can shoot air down under your keys and force out any dust that is trapped in the keyboard itself, making your board look fresh and new.
  
  

All-Purpose Cleaner

• If sticky grime or other dirt that can't be cleaned by compressed air has gotten onto your keyboard, a wipe-down with multipurpose cleaner may return it to its former glory. Spray some multipurpose cleaner on a soft cloth, unplug your keyboard and run the cloth over the top and around the sides of your keys. Never spray this cleaner directly onto your keyboard, as it could seep between the keys and ruin your equipment.
  
  

Rubbing Alcohol

• If some serious misfortune has befallen your keyboard and it is in need of major cleaning, rubbing alcohol should be your tool of choice. If, for example, you spill a sticky-yet-delicious slushy on your keyboard, the only way to truly return it to its former state is to remove the keys and clean the base with isopropyl alcohol. When performing this cleaning, don't dump the alcohol directly onto the keyboard; instead, apply it to a cotton swab and gently run it around the board base until it is clean.
