Mobile phones have become an extension of our hands, but we rarely think about how many germs they accumulate. According to technology and health experts, these devices can host hundreds of microorganismsfrom harmless bacteria to potentially harmful viruses.
Every day we touch the mobile screen dozens of times, even in places where we would normally take extreme hygiene: the kitchen, restaurants or the bathroom. Recent studies have shown that phones can contain a surprising microbial diversity. Although not all of these organisms cause disease, the possibility of transmission existsespecially when the device comes into contact with our hands, face or food.
Unlike hands, which are washed several times a day, the phone is rarely cleaned properly. This carelessness turns the device into a potential vehicle of contagion, especially when shared with other people.
Products you should avoid
Many users turn to common household products to disinfect their phones, but this practice can cause irreversible damage. Manufacturers such as Apple or Samsung advise against use of bleach, vinegar, glass cleaner or alcohol with concentrations greater than 70%. The reason is that modern mobile phones include an oleophobic layer, a film that repels fingerprints and stains. Aggressive substances such as ammonia, acetone or certain alcohols can deteriorate this layer, reducing touch sensitivity and leaving the screen more exposed to marks.
The vinegarcommon in home remedies, can corrode the edges of aluminum or plastic, while products with peroxide or chlorine are too strong for electronic materials. Paper cloths are also not recommended, as they can scratch the screen or leave residue.
The right way to clean your device
Cleaning your phone without damaging it is easy if you follow the proper recommendations. The first thing is to turn off the device, disconnect accessories and remove the case. Experts advise using soft microfiber cloths and 70% isopropyl alcohol wipesnever directly on the screen but slightly moistening the cloth.
For delicate areas such as the speaker grills or the charging port, you can use fine bristle antistatic brushes.
Precautions and cleaning frequency
Liquid should never be sprayed directly do not submerge the devicealthough it is waterproof. Over time, gaskets and protective coatings lose effectiveness, so the ingress of moisture could cause short circuits or internal corrosion. It is also not recommended rub hardsince mechanical wear can remove protective layers.
Regarding the frequency, weekly cleaning is sufficient for normal use. However, if you take your cell phone with you to crowded or high-risk places (such as hospitals, gyms or public transportation), it is advisable to disinfect it more regularly.
