Schmuddel-Phone: How your phone frees your phone from viruses and bacteria


The coronavirus epidemic has reached Germany. Those who have not yet made hamster purchases or appear in public with a gas mask could apparently resist the scaremongering. But there are really useful tips on how to protect themselves from infection or curb the spread. While who has issued a series of advice on protecting against the virus and warned against false information on the web, all health authorities agree that mobile phones are still virus and bacterial slingshots. In recent days, the issue has repeatedly re-emerged on social media. Smartphone owners sometimes resort to aggressive disinfectants to rid the phone of germs. But caution is needed. With these cleaning agents, you can clean your smartphone without damaging it.

The smartphone is always at the start: on the train on the way to work, in the restaurant or on the toilet for a pastime during all business. With our hands, we also touch everything: in the supermarket, the subway or public toilets. Washing your hands afterwards is important, but what we often forget is that the smartphone collects all the germs and bacteria that our hands come into contact with every day. Flu viruses, diarrhoea bacteria, pathogens: The list of unwelcome smartphone residents is long.

You should not use these products

There are a number of quirky smartphone cleaning methods that you shouldn’t heed. For example, in a forum I found an Internet user who recommended the use of Coca-Cola because the popular drink had proven itself when cleaning silver cutlery. Seriously, there are liquids that you can use to clean the metal case, but are not particularly beneficial to the screen. In addition, most smartphones are now waterproof. But many smartphones can’t withstand liquids such as drinks or other solutions. Cleaning cloths are more suitable here: Lysol or Clorox wipes can be used for the back of the device, but their effectiveness ends there. Avoids in all cases the use of bleach, vinegar (very popular for cleaning in the household, as it is more ecological), fuel spirits or even more stringent disinfectants. These products could damage the display by attacking the grease-repellent coating (often used by manufacturers against fingerprints).

Everyone knows the eyeglass wipes that can be bought in supermarkets. They are also used to clean tablets, smartphones or laptop screens. But the little cloths can do nothing against germs. Other Internet users recommend the use of compressed air. However, great care should be taken in this unusual way of cleaning, as compressed air can damage loudspeaker and microcomponents.

We clear up two misunderstandings that are circulating on the net: First of all, the idea that you should only clean the screen. This proposal is completely wrong, because why shouldn’t the back of a smartphone get dirty? Then the thesis that the smartphone should be cleaned underwater. This theory is not only wrong, but also dangerous, because soapy water could also penetrate a waterproof device.

Cheap cleaning kits

There are various products that you can use to clean your smartphone. There is no miracle cure, but some products may fit better with the model you use than others.

This kit comes with instructions to help you better detect dust and dirt in the nooks and crannies of your phone. It includes antistatic sponges and cotton swabs.

This pack of 60 wipes can be used as a supplement to the above kit. Each wipe is quite effective against fingerprints and does not attack the protective layer.

Step by step to a clean smartphone

  • Removes any shells under which germs can accumulate
  • If the (waterproof!) Case made of plastic or glass, rinse once with water (without soap) and let it dry in the air (no hair dryer, heat damages the smartphone). For smartphones with leather back, special cleaning agents for (art) leather should be used carefully
  • Uses a smartphone cleaner and cotton swab to clean the edges of the upper speaker, the speaker grilles
  • With a soft toothbrush, clean your USB-C or Lightning port so that no fibers of the cotton swab are left behind
  • The display best cleans your with smartphone cleaner and a microfiber cloth
  • The phone should be completely dry before you put it back in a protective case

Ultraviolet disinfection

Unfortunately, the above methods do not kill stubborn bacteria and germs, but only clean superficially. This works with the following product: the risk of the spread of the coronavirus has led citizens to equip themselves with masks, antibacterial gels, disinfectants and more. Cleaning products for smartphones are relatively cheap compared to certified masks (which also bring little) in medical quality. This year, a new article has been published that could be suitable for those who want to put money on the table for cleaning the smartphone. It is an ultraviolet cleaning kit that does not damage the display, but is intended to rid the smartphone of any germs and bacteria. The promise is that ultraviolet light can kill bacteria and disinfect the phone within minutes.

The gadget is a bit reminiscent of a sunbed studio. In fact, the mobile phone is to be disinfected using UV radiation. The “mobile shower” cleans the device and a light indicates when the process is complete or still in progress. As soon as the light goes out, the phone is clean and ready for use, according to the manufacturer. Some users even use this device to clean their keys.

According to a British study, we average our smartphone 221 times a day. And how often do we clean the phone? Discussed with us: Do you have other methods for cleaning your smartphone or do you never clean it?
