How to Clean your Computer Keyboard


It is essential to clean your computer keyboard regularly because keyboards attract dust, retain dirt and even carry germs. If the keyboard is used by several people, it easily becomes a harbor that facilitates the transmission of microbes from everyone’s fingers; even with a single user. Your keyboard is the receiver or transmitter of everything our fingers pick up during the day, despite hand washing.

A very serious British study showed in 2008 that there are fewer harmful bacteria on toilet bowls than on computer keyboards!

Here is how to clean your computer keyboard:

1) Before you start, turn off your computer and unplug the keyboard.

2) Turn it over and shake it, preferably outside, to let the crumbs fall out.

3) Send pressurized air between the keys with a Pressurized Compressed Air Duster;

If you do it indoors, do not forget to clean the surface on which the keyboard was cleaned with a damp cloth or with a vacuum cleaner.

Note: you can order Pressurized Compressed Air Dusters by sending an e-mail at

In the absence of compressed air, you can use your vacuum cleaner by setting the power to the minimum so as not to damage your keyboard.

4) Finally, clean the keys one by one with a soft cloth slightly moistened with alcohol. Take the opportunity to also clean your mouse and cables. Note: be careful not to over soak the cloth and do not drip liquid on the keyboard! To remove black marks on the keys, use a cotton swab dipped in methyl alcohol (methyl hydrate). It is recommended to clean your computer keyboard every 2 months, or every month if you use it a lot; some users, more concerned with hygiene, take a few seconds every day to clean their keyboard with a damp cloth, preferably at the beginning of the day. Advice:If you happen to eat in front of the computer, move your keyboard away so crumbs will not fall between the keys. Also make sure to keep your coffee or other liquid away from your keyboard: this is a common cause of irreparable damages. This cleaning can also be applied (depending on the architecture of keyboards) to laptops, telephones, cell phones, calculators, ATMs, ticket windows, alarm system modules with keypad, intercoms and the likes.
