It often happens that the smartphone display is dirty or greasy due to fingerprints: here’s how to remove them from your mobile phone
Phone screens get dirty easily because we use them so oftenor. This continuous wear damages the oleophobic treatment that serves to protect the display from Fingerprints. Furthermore, if the protective film that you use on the screen is not oleophobic, it is even more likely to get dirty due to fingerprints.
Today, smartphones have become indispensable in our lives. We use them everywhere and to do so many things. Most modern smartphones have one touch screen, which means we constantly touch it with our fingers. This continuous contact causes fingerprints and marks to accumulate on the displaydue not only to dirt but also to the sebum we have on our skin.
To keep our smartphone screen clean, it is important to choose appropriate accessories. We are talking about oleophobic protective films, which help reduce fingerprint buildup and keep the display cleaner for longer. But not only that: let’s find out how to remove fingerprints from your smartphone.
Fingerprints on your smartphone display: here’s how to eliminate them
Oleophobic coating is usually present on today’s smartphones, that is, the modern ones. This special layer protects the screen, makes it smoother and reduces fingerprints. The term “oleophobic” comes from Greek and means “oil-repelling”.
This type of display was introduced for the first time the iPhone 3GS in 2009. Science writer Bill Nye explained that the coating works by chemically bonding an oleophobic polymer to the display glass using an intermediate molecule called “Silane”. This process creates a barrier that repels skin oil.
Unfortunately, the oleophobic coating doesn’t last forever. Over time and continuous use it wears out and becomes less effective. Apple, for example, admits that this coating wears out with normal use. To slow this process, it is important to avoid harsh cleaning products such as bleach or hydrogen peroxide. It is best to use products with a70% isopropyl alcohol or 75% ethyl alcohol, which are approved by the manufacturers. In most cases, a simple microfiber cloth is enough to clean the screen.
You should also avoid using strong chemicals that can damage the oleophobic coating. By keeping the screen clean and treating it with care, the coating can last longer but above all we can keep it clean for longer. In fact, the fingerprints that often form on them are truly unsightly. Another trick to know, now that we are approaching summer, is how to remove sand from the screen.
