Coronavirus (Covid-19): How to clean your smartphone

Your smartphone is your daily companion and therefore spew huge quantities of pollution. Especially these days some hints on how to clean your smartphone the right way:

Please do not say that you are currently reading this article on the toilet. Not out of the author's vanity, but for the sake of hygiene. The coronavirus is increasingly in the public focus. And if you look at some hamsters on the soap shelf, washing your hands may not have been heard as you thought. Another case is your own smartphone.
Smartphone cleaning - How to do it right?
After all, this is a daily companion. Peter Hall, a public health expert at the University of Waterloo, called the smartphone "The Conversation" a "walking petri dish". Germs, bacteria, and viruses feel comfortable on it - even more comfortable than on a toilet. Experts estimate that there are ten times as many bacteria on a smartphone as there are on toilet glasses, and fecal matter is found on every sixth. It is, therefore, necessary to clean the cell phone regularly. But how do you actually do this correctly?

Google and Apple explain how to do it

The top dogs provide their own instructions for this on their websites. Apple recommends its iPhone customers to first disconnect all cables. Then you should use a soft, slightly damp, lint-free cloth.

Google has similar tips for the Pixel series. A dry cloth is best for most stains or dust. For most paint residues, for example from make-up or new jeans, you should use a damp cloth. Michael Schmidt, microbiologist, and immunologist at the Medical University of South Carolina, advises users on "Slate" to clean the smartphone every time after being in public. "Whenever it was at risk," said the expert.

Don't destroy protective layer on the display

But be careful: Because modern displays are usually provided with an oleophobic (oil-repellent) coating. This is to protect the screen and prevent fingerprints, for example. So you should not exaggerate and do not use aggressive cleaning agents, such as window cleaners. Otherwise, there is a risk that the oil-repellent coating degrades even faster. And even if modern devices are called water-resistant, you shouldn't keep them under the tap. The connection openings must be completely dry before inserting a cable again.

About toilet break

And what about the toilet now? According to a study by the tech company Vital Vio, 88 percent of the 1,200 US citizens over the age of 18 surveyed use their smartphones on the toilet. One should rethink this behavior for two reasons: On the one hand, excretions such as urine or stool in corona cases could also be infectious. On the other hand, you usually hold the cell phone at the toilet close to your face. This is also problematic because the virus finds its way into the body through the oral or nasal mucosa and the conjunctiva. Schmidt, therefore, recommends that you keep your cell phone in your pocket when going to a public toilet.
If this is too late in your case, you should at least take this to heart next time. And of course, you should also regularly clean other technical devices. For example, if a keyboard is used alternately by other people.
