They can get out the dust in that random corner of your keyboard that you didn’t even know you had. And what makes them most amazing and useful is the fact that they are like a power cleaner for your keyboard.

Compressed air, which is exactly what its name implies, comes in a can and can be purchased at any office supply store, super store, and even on Amazon. Allow the keyboard (and keys) to completely dry before turning back on. If possible, remove the keys and soak them in water with a mild soap. These particles, combined with any miniscule food crumbs, are nearly impossible to remove with gentle shaking alone. Using a disinfectant wipe or a cloth with rubbing alcohol, lightly wipe down your keyboard surface to kill germs. Just like any piece of furniture that sits in one place for a long time, the spaces in between your keyboard are going to gather dust. This debris removal is an important first step because it gets the big, bulky stuff out so they won’t get in the way of your more precise scrubbing action later on. In the case of a standard film keyboard that has become greasy, it is not easy to remove the keycaps. Once dried, you can put back the keycaps. Once cleaned, allow the keycaps and the main body to dry. (If your device is wired, simply unplug it from your computer.) Next, clean the outside of your device with a lint-free cloth lightly moistened with water. If your device uses removable batteries, remove the batteries.

Stand over a garbage can and gently shake your device so that any dried up crumbs or pieces of food will fall out, thanks to the handy force of gravity. For removing the dirty stains on the keyboard’s main body, just wipe the body using a towel soaked in 99 alcohol. Apple wireless or USB keyboards, mice, and trackpads. With a good grip, carefully turn your laptop or keyboard completely upside down.
