There are some grease and fingerprints on the screen, what should I do? Since the epidemic, alcohol pads are always kept at home. I immediately tore a pad and wiped it casually, and the screen looked brand new.
But why do people always say “Don’t use alcohol to clean the computer screen”! There are often netizens who say that after wiping the computer screen with alcohol, the screen is seriously damaged.
Then all kinds of popular science came out, some said that using alcohol would damage the screen coating, and some said that alcohol would directly corrode the screen.

Is alcohol so terrible? Why have I been fine for so long? What if you want to wipe your phone and disinfect it?
wipe it and it will be broken
It’s not the screen, it’s the coating
If you go to the Internet to search “can you use alcohol to wipe the screen”, almost all the articles with the answer “no” will mention the coating. Regarding whether it can be wiped with alcohol, here is the conclusion: there is nothing wrong with the screen of the mobile phone, and it is not recommended to use it on the screen of the computer or TV .
The coating peeling off on the surface of the display丨appleinsider
For TV and computer screens, in order to avoid reflection and improve the display effect, a layer of “anti-reflection coating” will be coated on the surface of the screen. However, this coating does not “integrate” with the screen, it “sticks” to your screen like a film.
The coating materials designed by different manufacturers are not the same. Alcohol, as a good solvent, will indeed damage the soluble coating , resulting in uneven brightness of the screen and visible coating peeling off. Moreover, non-touch computers and TV screens generally do not have fingerprints, so manufacturers generally recommend that they be wiped gently with a soft cloth dampened with water .
It seems that it is not a big problem not to wipe the computer with alcohol, but as a mobile phone that is often taken out, can it be disinfected with alcohol? As a touch product, mobile phones usually add a “hydrophobic and oleophobic coating” on the surface of the screen to avoid becoming a “fingerprint collector” and affecting use. The current common hydrophobic and oleophobic layer uses fluorine-containing coatings, which are stable and will not react with alcohol . In the official cleaning guidelines of Huawei and Apple, it is mentioned that alcohol soft cloths and wet wipes can be used to clean the screen .

let you wipe with alcohol,
Didn’t let you spray alcohol directly!
No, the computer screen in the media reports is not just as simple as the coating is gone, the entire screen cannot be displayed normally at all.

Almost no company would recommend that you spray alcohol or cleaner directly on the screen, not even water! Although the current equipment integration is doing well, and some of them have reached a high waterproof level, this does not mean that you can directly pour alcohol on it.
Spray directly on the screen, and the liquid may flow to the edge seams, thereby infiltrating into the inside of the machine. Even if it is a waterproof device, the waterproof glue at the seams may be dissolved after encountering alcohol or detergent .
The correct way to clean it is to spray the cloth丨samsung.com
So no matter what screen is cleaned, if you need to use liquid (water, alcohol, detergent, etc.), you should spray the liquid on a clean soft cloth , and then wipe the screen when you gently pinch the cleaning cloth so that no droplets can be squeezed out.
The key is not alcohol
but what kind of cloth
You may think that whether you wipe the screen with alcohol or not, your phone will always become more and more “greasy”. The biggest killer for most screen coatings is not alcohol, but friction .
Cleaning guidelines for almost all brands specify what wipes to use for cleaning: Use a soft, lint-free cloth (such as the one that came with your computer when you bought it), and avoid harsh cloths, towels, paper towels, or similar items .

In fact, the effect of the screen coating itself will weaken over time. If rough cloth or paper towels are used, even if the screen is wiped directly with clean water, the coating may fall off due to excessive friction .
At the same time, for notebook computers, if you use a keyboard membrane, the protruding keyboard membrane will directly touch the screen when the lid is closed. If the material of the keyboard membrane itself is rough, or there are relatively hard dust particles left on it, it will damage the coating. wear and tear.
For new equipment that has just been purchased, excessive cleaning is not required, and it is most important to use a suitable soft cloth for cleaning . For old equipment, various “repair films” can be purchased online. In fact, it is essentially to form a layer of coating on the surface of the screen, but this method does not last long .
If it really affects the normal use, you can go to the brand’s official after-sales consultation and apply for replacement services.
Do not wipe it unless necessary!丨pixel
To put it simply, if it is for cleaning purposes, there is no need to use alcohol . Just use a soft cleaning cloth to wipe the screen. If necessary, you can wet the soft cloth and squeeze it dry until it does not drip.
For the purpose of disinfection , both Huawei and Apple have stated that alcohol pads can be used to wipe and disinfect the screen of the mobile phone , but it is necessary to prevent alcohol from entering the pores. At the same time, please do not use alcohol if there is a leather back cover.
Oh, if you have pasted a film, feel free to use it boldly, at worst, re-paste one.
By the way: Computers, TVs and other large-screen products are more stringent in the pursuit of visual effects, and the coatings used by each company are different. You need to refer to official documents or customer service consultation. (e.g. Apple’s nano-textured glass display can only be cleaned with the polishing cloth that came with the Pro Display XDR or iMac)
