It’s more useful to consider the environment you’re in and how the microbes are transmitted. “Many nasty microbes, even though you can find them in the environment,” will not be transmitted and cause disease just by their mere presence on an object such as your keyboard. But lets take a look inside your laptop.
There hasn’t been a lot of research into disease transmission from personal devices, but a recent study found no evidence that keyboards transmit disease, even in places that harbor lots of nasty microbes, such as hospitals. A 2019 paper that examined contamination on keyboards in health-care settings found that the majority of devices contained many microbes, including some pathogens, but researchers couldn’t find evidence of an impact on patients and workers.
Probably someone from the government should look into this.
Being in IT for over 20 years and digging around the insides of computers you observe things.
The insides of a laptop duplicates the environment it is in
With the recent outbreak of the corona virus, I started to make some observations.
laptops have gotten so disgusting to me in the past that I have even instituted a "roach fee" for machines that are presented to me with live insects inside.
Both helpful and harmful microbes exist everywhere, and trying to eliminate all microbes from an environment isn’t possible; you’d have to live in a bubble, he said. “This is not about eliminating risk, it’s about reducing risk,”
To clean screens, touch pads and exteriors, move a flat-weave microfiber cloth in an S pattern, starting from the top corner and zigzagging down to the bottom of the screen to avoid streaks and to cover larger areas, Maker says. A dry cloth should be enough to get rid of most fingerprints and smudges. You can moisten the cloth with a little water or a mix of water and mild soap. Put your index finger in the cloth and buff spots away using a circular motion. A little isopropyl alcohol (Maker uses 70 percent), which dries on contact, lifts away stubborn stains, such as adhesive residue or coffee spots.
To clean keyboards, gently wipe the keyboard with the cloth. Use compressed air and a soft-bristle toothbrush or cotton swab to free large particles such as dust or crumbs from between the keys. “Use short blasts and use the straw nozzle to direct the air,” she says, and hold the can about three inches away from the keyboard. You can also go over each key with some isopropyl alcohol on a swab.
