According to Dr. Charles Gerba, professor of microbiology at the University of Arizona, constantly touching the phone explains why a phone often carries 10 times more bacteria than a toilet. With the current complicated COVID-19 situation, you should take the time to pay more attention to your phone.
1. Is alcohol necessary to clean your phone?
Citing a study, Dr. Somani pointed out that the virus can survive on common phone materials such as glass, metal and ceramic "about three days on average according to our local conditions, and the time may be shorter on aluminum.”
So what is the best way to keep your phone free of pathogens? Disinfectants like alcohol are the best way to kill germs. at least 60 degrees is needed for hand sanitizer, Dr. Somani recommends for your phone, the alcohol percentage should be higher than 70 degrees (that's the concentration that gives the most effective disinfection and has little effect). drying out the skin, of course, works for your phone too.) But why should that concentration be higher than the concentration in alcohol?It evaporates faster - and you also want the alcohol to stay on top. surface of your phone long enough to kill germs but not too long for it to affect the phone's material, she explains.

On the contrary some experts say that alcohol may not even be necessary when disinfecting phones. A 2013 study in the American Journal of Infection Control showed that a damp cloth was more effective than an alcohol swab at removing clostridium difficile - a bacteria that causes diarrhea - from iPad is contaminated. When it comes to eliminating antibiotic-resistant bacteria, methicillin-resistant Staphylococcus aureus or MRSA, using a cloth or cotton swab is equally effective.
We interviewed Dr. Dubert Guerrero, an infectious disease specialist at Sanford Health in the US and one of the authors of many studies who said that regularly wiping your phone with a damp cloth is a good idea. enough to eliminate common bacteria.
2. Why shouldn't you use alcohol?
We have proven that alcohol is very good for killing bacteria. But when it comes to disinfecting your phone, is alcohol the optimal solution?
In an article on CNET, James LeBeau, associate professor of materials science and engineering at the Massachusetts Institute of Technology, says alcohol can strip away the oleophobic (oil-repellent) and hydrophobic (water-repellent) coatings. on your phone screen.
He recommends avoiding the use of cleaning products such as Windex, alcohol and disposable wipes as they contain alcohol. If you find it necessary to use it, it is recommended to use it on your phone case, which is where our hands come into contact with the most. But read the instructions carefully as some cleaning products can corrode your phone case.

Although there are phones that are water resistant (can withstand water up to 1.5m for 30 minutes) like Samsung's Galaxy Note 10 series, Huawei's P30 Pro and Pixel Pixel 4 and 4 XL, pages Their official website says nothing about washing the phone under running water or using detergents for cleaning.
Phone manufacturers like Apple have also advised against using a stronger method than a soft, lint-free cloth along with warm water and soap. Samsung, too, advises users to use a "clean and soft cloth" without mentioning the need to use cleaning products. Google specifies to avoid using harsh cleaners, to avoid getting moisture or soap in the holes of your device, and to avoid spraying cleaners or compressed air on your phone.
3. If you insist on using cleaning products
If you're not confident that using a damp cloth is enough to wipe bacteria off your phone's screen, Dr. Gerber recommends mixing one part rubbing alcohol (70 degrees alcohol) with water. It still contains a percentage of alcohol but it has been diluted to minimize its effect on screen coatings. Use these freshly mixed solutions on a cloth, use that cloth to clean your phone screen. Do not pour or spray directly on the phone screen.
In addition, you should use cleaning products that are stated on the product label as safe to use on electronic devices including smartphones, tablets and remote controls. Note that using any cleaner on your phone voids the phone's warranty.

Another way to solve this problem, is to stick on a cheap screen protector (not the one with oil resistant properties). If it gets corroded by alcohol or cleaning products, you can replace it and it's much cheaper than buying a new phone.
In addition, there is a sanitary device called PhoneSoap that was featured in the TV show titled Shark Tank practical business. It is said to kill up to 99.99 percent of bacteria living on your phone and phone case with UVC in 10 minutes. Because of the mechanism of using light, it promises to bring efficiency to every nook and cranny that the use of wipes containing alcohol cotton cannot. Although we haven't tested using it, some sites like CNN recommend it.
Along with washing hands and wearing a mask , cleaning items such as phones is necessary to protect you from pathogens. For phones you can use a cloth along with a little warm water and soap. If using alcohol-based solutions, it is recommended to use products with a concentration of less than 70 degrees and combine cleaning on phone stickers or phone cases to avoid these cleaning solutions affecting the phone. your phone.
