Due to the epidemic of COVID-19 Coronavirus (ex 2019-nCoV), we would like to give you some tips for cleaning and disinfecting your smartphone screen, headphones, gamepad, touch pad, keyboard or mouse. .

Hard to miss, an epidemic of Coronavirus COVID-19 (ex 2019-nCoV) has spread from China. The basic sanitary instructions of the government are to wash your hands very regularly, avoid popular places and to cough or sneeze in your elbow.

As an additional measure, we wanted to explain how to clean your keyboard, AirPods, headphones, iPad or even the screen of your smartphone. These devices have surfaces that are nests for bacteria, microbes and other viruses…


You should already clean and disinfect your keyboard often, in addition to being a nest of germs, dust and dirt can have an impact on its performance and reliability.

Here are the steps to properly clean and disinfect a keyboard:

If your keyboard is wired, unplug it (USB port), if it’s a laptop keyboard or a wireless keyboard … turn off everything!

Turn the keyboard over to drop the dirt, you can tap it gently and shake it. For a laptop, we advise you to hold the screen (open) with your second hand;

Then use a bottle of compressed air to blow the debris, it’s less than 10 euros on Amazon;
Dip a cotton swab in a little isopropanol, you will find some on Amazon, pass the cotton swab between the keys;

Then rub the keyboard with a cloth soaked in isopropanol (a cotton square works too), you can then pass a microfiber cloth to remove the isopropanol. If you don’t have isopropanol, you can use an antiseptic wipe.

For your information, isopropanol (isopropyl alcohol) is an alcohol used for disinfection, but also as an antiseptic. Be careful though, this chemical compound is flammable and irritant. It must be kept away from heat and any flame. We also advise against breathing it, it causes headaches and dizziness.

For your mouse or your gamepad, use an antiseptic wipe or a cloth soaked in isopropanol, after having unplugged it obviously. Gently wipe the wipe or cloth over the assembly. You can then wipe it with a microfiber cloth or a simple clean tissue.


The smartphone is a nest for bacteria. Studies have concluded that there are more bacteria on your screen than on a subway bar or a toilet bowl … Yet you touch your smartphone on average every 10 minutes.

This is the problem of all touch screens, in particular the screens of public machines such as ATMs. Fortunately, if you can’t disinfect everything, you can disinfect your smartphone.

To avoid scratching the screen of your smartphone, you will have to be careful!

We do not recommend using a window cleaner, household detergent, compressed air, aerosol, solvent, ammonia or an abrasive or containing hydrogen peroxide (hydrogen peroxide) to clean your smartphone or tablet.

Touch screens are often protected by an oleophobic coating. If you do it wrong, you risk degrading this very useful coating;
Unplug everything and turn off your smartphone or tablet;
Wash your hands ;

Depending on your smartphone, you can use an antiseptic wipe or a cloth soaked in isopropanol. You can also use an alcohol-based gel on a clean paper towel;

Finally, pass a microfiber cloth in small circles. To wash the microfiber cloth, soak it in warm water with soap. Hot water is used to open the fibers and release the dirt contained in the microfibers. Do not wash your screen until the cloth is completely dry (or slightly damp) to the touch.

To avoid scratching or damaging it, you can also simply use a microfiber cloth. Unlike paper towels, microfiber cloths gently clean the sensitive screen of your smartphone or tablet without the risk of scratching it.

Be aware that the Corning Gorilla Glass coating that equips almost all high-end smartphones is mineral glass, tempered glass of alkali alumino-silicates. You can clean it with any household product without risk. However, some manufacturers advise against the solutions mentioned above. If you have a screen protector, you can use an antiseptic wipe.


To go further, know that you can also disinfect your smartphone by UV (ultra-violet) radiation. A unique feature of UV light is its range of specific wavelengths, between 200 and 300 nanometers (billionths of a meter), which are considered germicidal, which means that they have the ability to inactivate micro- organisms such as bacteria, viruses and protozoa. There is a specific product for smartphones called PhoneSoap… but which costs a fortune.

We also recommend that you disinfect your AirPods, true wireless headphones and other headsets. To do this, use a cotton swab moistened with isopropanol or an alcohol-based gel. A microfiber cloth will then come in handy for the outside and the charging case, while the cotton swab works well for cleaning the speaker grilles. You can also use a toothpick to dislodge certain residue.


Let’s finish with some bad advice that you absolutely should not follow:

Do not spit on your screen to clean it, you will make it even more dirty;

Do not press too hard on your screen, you may damage it;
Do not use a paper towel or tissue paper. These contain wood fibers which can damage your screen;

Avoid spraying water directly on the screen (for example under the water tap), even if your smartphone is water resistant (it is not resistant to water pressure);
Again: do not use abrasive products.
