We always unconsciously touch our eyes, nose, or mouth and other body parts. At the moment of the epidemic, there is inevitably a risk of infection.
Therefore, professionals recommend that you wash your hands and use alcohol-free hand sanitizers or alcohol sprays. Some people say that wearing a mask not only filters air, but also reduces the frequency of touching your face, thereby protecting yourself. Protected against viruses.
But don’t forget, your mobile phone is also the item you touch the most every day. How serious is this dependence? According to the statistics of research company Dscout, the average user clicks on the mobile phone on an average of 2617 times a day, and 10% of these heavy users even go up to 5,427 times.
It seems that our comparison of mobile phones as ‘extension of the human body’ is not an exaggerated statement.
However, more people are concerned about whether the virus can also be transmitted through mobile phones. A paper in the Journal of Hospital Infection pointed out that coronavirus can survive on the surface of inanimate objects such as metal, glass or plastic for 9 days ——If there are bacteria on the phone, it also means that you will touch them and even transfer to your face.
If you want to do a good job cleaning and disinfecting your mobile phone, before you start, you may want to know what you need to pay attention to.
Whether or not to wipe the phone with alcohol may be the first concern for many people. Manufacturers, including Apple, have previously said that users are not advised to use cleaners with irritating solvents directly for mobile phone cleaning.
The reason is that some detergents or disinfectant wipes may contain higher concentrations of alcohol, which will cause the oleophobic layer or hydrophobic layer on the screen of the mobile phone to fall off, causing irreversible damage to the screen.
Recently, however, Apple made an update on the device cleaning guide official website, it indicates that the user can use the ‘70% isopropyl alcohol wipes’ or ‘ Clorox (Clorox) disinfectant wipes’ product to gently wipe the hard, non-porous Surface, such as a display, keyboard, or other external surface.
Apple does not recommend using bleach on iPhones and other company electronics, due to the risk of damage caused by the abrasive product.
The term “70% isopropanol” refers to a daily care disinfectant on the US market. It is similar to ethanol in that it is also a type of medical alcohol, but in addition to 70%, it is also 60%, or as high as 91%.
The same is said by LG in relation to bleach: “Bleach, chlorine, disinfectant or other cleaning products must not be used to clean the appliance, as it may damage the product and / or leave stains”.
I also looked at the “mobile phone cleaning” guidelines of several other mobile phone manufacturers. Among them, Huawei stated on the official page that users can take an appropriate amount of alcohol and spray it on a soft lint-free cloth, and then gently wipe the screen, back shell and sides of the phone, but excluding the hole, gap and flash area of the phone.
After wiping, let the phone stand for 5 minutes and wait for the alcohol on the phone surface to evaporate.
The Asus also has some limitations. According to the manufacturer, other popular liquids indicated against the new coronavirus should not be used, such as “alcohol gel, chlorine or any abrasive product to clean the smartphone”.
Followed by Google’s “Clean Pixel Phone” page, Google also recommends using a soft lint-free cloth to wipe the phone, and do not use wet water most of the time. If the screen is stained, you can consider using a special screen wipe or lens cleaner. You can also use soapy wipes on the side and back of the phone.
Specific to the disinfection part, Google said that users can use ordinary household disinfection wipes, or 70% isopropyl alcohol wipes, but do not allow cleaning wipes containing bleach.
Finally, Samsung, I asked the official customer service. The response from the customer service was also ‘Wipe with a soft cotton cloth or eye cloth‘. If the screen stains are not easy to wipe, you can also use a slightly wet cotton cloth, but alcohol is not recommended. To wipe the screen part.
However, Samsung’s customer service also added an exception, that is, mobile phone film. If you have the habit of sticking films frequently, you can use the wipes containing alcohol to wipe the screen more boldly. Anyway, the film is damaged, just change another one.
But people with protective shells may not be so willful. Unless you can change the phone case as often as the film, they will sooner or later become a carrier full of bacteria.
Another more effective method of disinfection is the use of ultraviolet light.
Recently, Samsung launched ‘Samsung Mobile Phone Disinfection Service‘ in 19 regions around the world. It is reported that offline stores in these areas will use UV-C short-wave ultraviolet disinfection lamps to disinfect user’s mobile phones, rather than cleaners with irritating solvents, so that mobile phones can be cleaned in a dry state.
At the same time, a UV disinfection box called ‘PhoneSoap‘ has also experienced a surge in sales overseas due to the epidemic. The company claims that the device can kill 99.9% of common bacteria such as E. coli and Salmonella that are attached to the surface of mobile phones, but has not tested the coronavirus.
Some research scholars believe that, due to the influence of irradiation intensity and irradiation time, a small box like PhoneSoap cannot completely eliminate the coronavirus in a short time. Unless the user allows the mobile phone to be exposed for more than two hours, the dose is completely insufficient.
In contrast, experts believe that wiping the phone with a minimum of 60% alcohol may be a more practical disinfection practice.
Based on the expressions of several manufacturers, the simplest and safest method of cleaning and disinfecting is still directly using a lint-free soft cloth or microfiber cloth with water to wipe the screen. Of course, you can also use the special Zeiss or iKlear special detergent.
For deeper disinfection, you can consider using a disinfecting wipe with a concentration of less than 70% alcohol, but it is still recommended not to wipe it excessively, as this will also cause screen damage.
Here are some tips and tricks related to cleaning your phone. For example, mobile phone manufacturers do not recommend that users spray liquid directly on the mobile phone when cleaning, but should spray liquid on a soft cloth before wiping the mobile phone.
How to clean your cell phone against the new coronavirus
Cleaning your phone requires special care. In addition to the procedure, some chemicals can cause irreversible damage to electronic devices.
It is important to use only those recommended by the manufacturers:
- Soft, lint-free cloths;
- Microfiber cloths (recommended by Samsung);
- Isopropyl alcohol with 70% concentration;
- Ethanol alcohol with 70% concentration (recommended by Samsung);
- Clorox cleaning wipes (recommended by Apple).
Now that you know which products to use, learn how to clean your phone:
- Turn off the phone;
- Remove all accessories and cables from the cell phone;
- Leave the cloth slightly damp with the appropriate cleaning product;
- Pass the cloth gently over the external surface and the screen of your cell phone;
- Let it dry for a few minutes before turning it on again.
- Remember that hands should be washed with soap and water after the process.
Accessories, such as covers , must also be sanitized. The process, however, may vary depending on the material used in the case you chose.
What shouldn’t be done when cleaning the phone?
Some practices should also be avoided.
After all, we want the cell phone to work after all this, don’t we?
- Do not clean with the cell phone on;
- Do not immerse the phone in cleaning products – regardless of whether it is water resistant or not;
- Never spray cleaning products directly on devices;
- Avoid compressed air, bleaches, abrasives and other products not recommended by manufacturers;
- Avoid moisture in the device’s inputs (USB, headphones and the like);
- Do not press the cloth hard on the screen or other parts of the phone.
It is not recommended to throw the phone directly into the water, or to wash it under the faucet. Even some phones support IP68 waterproof, but it is still necessary to avoid the speaker, data interface and other places getting wet when wiping, or let the phone be wet. The liquid penetrates into the inside of the phone through the opening.
A reasonable approach is that after you wipe your phone with a clean wipe, it is best to use a dry flannel for a second wipe to avoid leaving water stains on the glass.
Some people may think of using rough cloths, towels, paper towels, etc. to replace soft velvet cloth, but these items are not recommended by Apple, mainly because the surface of ordinary paper towels is relatively rough. If you wipe the screen for a long time, there will be scratches. risk.
For the dirt on the earpiece, speaker and interface, a thin cotton swab is the easiest tool to find. You can also use sticky ‘blue butadiene’ to solve it. I personally do not recommend using sharp objects such as toothpicks, paper clips, etc., because accidental damage to the handset or interface contacts may be possible. Of course, you can also trust your processing technology.
In addition, sprays, bleaching agents, abrasives, and even laundry detergents cannot be used directly on mobile phones. This is also due to the existence of an oil-repellent layer on the screen. If the oleophobic layer is frequently exposed to chemicals such as alcohol, the coating will peel off more quickly.
Cleaning your phone doesn’t mean that you can completely isolate the virus. In contrast, frequent hand washing, wearing a mask, and staying away from crowds may be more helpful in reducing the risk of contracting the disease.
But if you can, it’s icing on the cake to wipe your phone and create a clean living environment for yourself.
