In 2016 research revealed that the average computer keyboard not only has hundreds of times more bacteria than a toilet, but also disturbingly aggressive bacteria.
Now, underestimating our smartphone's and keyboard's potential to cause illness is one thing. But not without being amazed by some findings:
Statistically, women's office keyboards are dirtier than men's. Unfortunately, the study by the University of Arizona did not provide any guesses of why. It is, however, an interesting finding.
Hospital keyboards are most critical. It makes sense, but we rarely think about it: A study at the Chicago Memorial Hospital found two deadly and drug resistant types of bacteria prone to sticking to the hospital's keyboards. Something that doesn't affect our personal work environment, but certainly something I will have in mind at the next doctor visit.
Well, it is suggested to wash your hands prior and after using a keyboard.
As for the cleaning: make sure you clean between the keys! Unplug your keyboard and turn it around to get rid of debris. Then, with a qtip and alcohol, carefully clean between the keys. Use a damp (not wet!) cloth with cleaner to go about the surface of your keyboard.
With mechanical keyboards, you normally can remove the caps easily.
