Dirty smartphones: cell phones provide an ideal breeding ground for bacteria
Most can no longer imagine life without a cell phone. It is a little surprising that the popular cell phones in particular are only cared for superficially, if at all, because only about 27 percent of cell phone owners clean the surface of their device consciously and intensively. This is the result of a current representative study commissioned by the industry association BITKOM, for which 1,000 people aged 14 and over were interviewed in Germany, including 891 cell phone owners.
Mobile phone care is largely neglected According to the study, the care of mobile phones is neglected, although there are no differences between age groups or men and women: Just under half (49 percent) of cell phone owners “only occasionally and briefly cleans it, for example by wiping it off on clothing, one in eight never cleans their mobile device ”and“ not even every fiftieth mobile phone owner cleans his device weekly, ”said BITKOM.
Smartphones are a pool for bacteria Smartphones therefore seem to be the ideal breeding ground for bacteria - precisely because they are used everywhere and everywhere: whether during meals, during sports or even on the toilet, in addition, the mobile phone is often also used by children or friends passed on, for example To show photos or videos. The surface of the phone quickly developed into a pool for bacteria.
Earlier studies had come to the same conclusion - for example, British researchers published a study in 2011 that every sixth mobile phone showed traces of faeces - the scientists had found residues of the E-Coli bacterium on these mobile phones.
Regular maintenance of displays and keyboards is important According to BITKOM expert Bernd Klusmann, smartphones, in particular, should be cleaned and maintained regularly, because "cell phones can transmit germs, and it is particularly useful to clean displays and keyboards during the cold period," says touchscreens Although very robust to be able to withstand everyday wear and tear, they would lose their cleanliness with the first touch: "Sweat and grease are deposited in tiny scratches that occur even when the cell phones are operated correctly," says the expert.
Tips for cleaning and caring for mobile phones In order to keep your mobile phone as free as possible from bacteria, regular maintenance is essential. According to the association, however, there are some things to consider so that there is no damage to the device in the end.
Even if the glass cleaner is close at hand - according to BITKOM, harsh cleaning agents like this are not suitable for cleaning touchscreen surfaces, because "dishwashing detergents and soapy water can damage the grease-repellent surface of the devices in the long term and thus impair their usability." Cell phones - like all other electronic devices - cannot be cleaned with water, because "penetrating moisture can corrode electronic circuits and permanently damage a cell phone."
The association also advises against cleaning with alcohol. Although this has a disinfectant and germicidal effect, “but it attacks the grease-repellent surface of the cell phones and should be used as rarely as possible.” Therefore, special hygienic sprays with a germicidal effect, which can be found in drugstores, pharmacies or specialist shops for around 2 euros, are generally better gives.
In order to protect the surface of the mobile phone, cleaning wipes made of microfiber should be used for everyday care, according to the association. Glasses cleaning cloths made of this material could also help here in an emergency. Because microfiber cloths, such as those found in drugstores or specialist shops, absorb grease dirt even when dry - but according to BITKOM, care should be taken during dry cleaning “that there are no coarse particles on the touchscreen: they can leave scratches when rubbed. "
If you want to protect your display and keep it as good as new, the association recommends using a special screen protector, because it offers several advantages: “It is barely recognizable, adheres without glue and protects the cell phone like a wrapping film protects a book. The film prevents the surface from being scratched and reduces the possibility of germs depositing. ”
But even if cell phones can become bacteria-collecting basins - according to BITKOM, this does not mean that the bacterial load itself must lead to illnesses. Therefore, regular, intensive hand washing is still the best protection against diseases, "because the largest transmitters of millions of germs remain unwashed hands," said the association. Most diseases would be transmitted in this way: "Because people touch their faces about every four minutes on average, pathogens enter the body through the mucous membranes of the mouth, eyes and nose and spread."
