Now almost every phone is equipped with an oleophobic coating. At best, it will last a couple of months, after which you will either have to put up with a bunch of fingerprints on the screen or put on a protective film. But maybe there is another option?

When buying a phone, few people pay attention to the presence of an oleophobic coating, preferring to immediately stick on a protective film or glass (if the manufacturer has not done so). The problem is that most users don’t bother and buy the most affordable Chinese films. After removing them, the entire oleophobic coating will remain on the film, which turns using the phone into real agony.

To be honest, I’m not particularly fond of all sorts of additional glass and films, so after several days of using the new phone, I got rid of the annoying element. But along with the film, this “magic” coating also went away. The search for a solution to this problem led me to a forum where they advise using car polish to imitate oleophobic properties.

But I know that such products, even though they are made on the basis of soft abrasives, are still capable of harming the protective glass, and their long-term use can completely scratch off the glass (possibly the appearance of depressions or irregularities on the surface). And you don’t want to constantly come into contact with automotive chemicals on your skin.

I came to a solution to this problem while cleaning the house. To wipe wooden surfaces, I use a special polish, which covers the surface with a special protective layer. Plus, it is completely harmless to human skin. So after a couple of minutes of thinking, I tried applying it to the glass of my phone. The result pleasantly surprised me.

So, we need any household furniture polish (preferably not the cheapest one), microfiber and a “problem” phone.

We first clean the phone from dirt so that the screen is perfectly clean. Then apply a small amount of the product to the microfiber and rub it lightly over the phone screen. It is better not to overdo it with the amount of polish, so that during application the excess does not get into, for example, the speaker holes.

Then you need to wait about 5-10 minutes for the protective layer to dry completely and wipe the screen again with a dry part of the microfiber.

We have before us a perfectly clean protective glass, which will repel grease and fingerprints for the next 3-4 days.

Yes, the effect of such a polish is not as long-lasting as we would like, but I don’t think that repeating this process several times a week will greatly complicate your life. But the phone is now much more pleasant to use. Yes, and it smells good. This option is perfect for those who have already worn off the oleophobic coating, but do not want to glue a protective film.

In the description of many smartphones you can often find the phrase "oleophobic coating" display/screen, but few people know what it is and how the absence of this coating affects the screen.

Oleophobic coating(oleum - oil and phobos - fear, fear) - this is a very thin film that is not visible, but thanks to it there are no fingerprints left on the screen i.e. Oleophobic coating repels fats and liquids from the touch screen (display).

Apple began using this coating in the 3rd generation (iPhone - 3GS). The idea was picked up by other mobile phone manufacturers. Currently, almost all manufactured smartphones have an oleophobic coating.

Over time, this coating wears off. To extend the life of the oleophobic coating, manufacturers do not recommend wiping the display surface with cleaning agents or alcohol-containing liquids.

An oleophobic coating can be applied to the screen yourself at home, but its resistance and durability will not be as good as that applied in a factory using modern technologies. For this reason, it is easier to install protective glass with an oleophobic coating or protective film.

Here are several ways to apply an oleophobic coating to your phone:

1. Apply water-repellent shoe spray to the screen.

This spray can be purchased at most shoe stores. But such an oleophobic coating does not last long; at best it will last a day.

Application order:

Seal all the holes in the phone with tape (which are made for the earpiece, microphone, i.e. seal all vulnerable areas so that the spray does not get there).
Apply the spray to the screen according to the instructions on the product packaging
Repeat the previous step 3-4 times, i.e. apply 3-4 layers.

2. Apply car wax to the screen.

You can buy the product at auto parts stores, but these products are not cheap and not all are effective.

Application order:

Wipe the phone screen (remove dirt, fingerprints and traces of grease) and polish the surface to a shine.
If necessary, seal all the holes in the phone with tape (which are made for the earpiece, microphone, i.e. seal all vulnerable areas so that the spray does not get there).
Apply the spray to the screen according to the instructions on the product packaging.

3. Use specialized tools.

You can also find products made specifically for cell phone screens, but these products are quite expensive and quite difficult to find on sale. Alternatively, you can order on eBay. Several options for such special equipment: “Fusso SmartPhone”, “Ultra Ever Dry”.

An oleophobic coating is a very thin film of nanometer thickness, which, due to its composition, repels fats and grease-containing dirt from the touch screen. In other words, it is a coating on the surface of the screen that prevents it from getting dirty. It is absolutely imperceptible with your fingers, but noticeably cleans glossy display surfaces. The name of this protective layer is derived from the Greek word “oleo”, which means “oil”. The oleophobic coating contains 0.1-10% alkylsilane, 0.01-10% silicone and some solvent.

Until a few years ago, coating was applied using heat. Now there are two technologies that allow you to maintain normal temperature. When using the first, the oleophobic coating is applied by vapor deposition. The second method is based on the use of silicon dioxide. In both cases, the coating composition is applied by spraying, which has a positive effect on the quality of the coating.

History of oleophobic coating

This type of protective coating was invented by German scientists Melanie Hoffmann, Jonker and Owers. On July 25, 2005, they patented their coating, and a little later Apple applied for a patent for an improved coating.

Since 2012, it has been used in smartphones. The very first phone to receive an oleophobic coating was the iPhone 3GS. After that, it began to be used by other manufacturers. Today, this coating is applied not only to device displays, but also to protective films for the same displays.

Preservation of oleophobic coating

With its nanometer thickness, the coating is susceptible to abrasion. This can happen for various reasons. Firstly, the protective layer is erased when using the phone in games that are controlled by frequent touches to the device’s display.

Secondly, the device does not have a cover, and the display is constantly in contact with clothing, the lining of a bag, etc.

In order to prolong the use of the oleophobic coating, you should not leave the device in the open sun, allowing it to heat up. It is also not recommended to wipe the display with various cleaning agents that contain alcohol-containing liquids or any abrasives.

Tip 2: How to restore the oleophobic coating on your smartphone

Oleophobic coating is a special protective composition applied to the screen of a smartphone or tablet. Thanks to this coating, the screen is able to repel water, various oils, dust, and also prevent the appearance of fingerprints. A good oleophobic coating not only allows you to easily remove any traces from its surface, but also has anti-reflective properties. Unfortunately, it is short-lived and wears off over time.

Almost all modern smartphones are equipped with an oleophobic coating. It not only protects the device from dust and dirt, but also makes the touch display a little slippery. This is precisely what is very important for comfortable use of a smartphone. The thickness and quality of the protective layer differs from model to model, but on average, it is ready to serve faithfully for just over a year.

To determine the wear of the oleophobic coating and the need to apply a new one, tactile sensations alone are not enough. A drop of water, carefully applied with a pipette to the screen, will serve as an indicator of the presence or absence of this protective layer. If the drop collects around itself and has an almost spherical regular shape, then everything is in order with the protective layer. A drop that has spread and taken on a pattern indicates wear on the screen surface.

If you are not a fan of using films and protective glasses, a kit for covering the screen with an oleophobic coating is waiting for you in any hardware store. It consists of a tube with a polymer composition and a soft cloth, which is used to evenly distribute the composition over the gadget’s screen. Before application, the display must be cleaned of dirt and oil stains. The whole process will take no more than 5 minutes.

Despite the fact that in the previous entry on our website, we did not find a real, working method, progress in the field of independently finding ways to improve the quality properties of your cell phone without having to buy a new one has not stood still.

On one of the Western forums, we discovered a simple and effective way to independently apply an oleophobic coating to the screen of almost any smartphone, regardless of its age, condition and remnants of previous coatings. At the same time, we repeated the method on several of our smartphones, using several tools at once - everything works, everything is cheap, almost free.

The secret turned out to be simple - to get rid of annoying fingerprints and grease stains on your phone screen, you need to buy car wax of the “Nano” category at the nearest auto store. Almost anyone will do. The need for the prefix “nano” in the name of the wax is not dictated by respect for progress in Russia, but by the fact that such packages usually sell finely dispersed preparations that most closely suit our goals and objectives.

Judge for yourself - the diagonal of a modern smartphone often exceeds 5 inches, which is equivalent to 26 centimeters. Screen areas measure in hundreds of square centimeters, so polishing a smartphone screen will correspond to polishing a small area of a car body. In this case, it is impossible to spoil anything. An oleophobic coating made independently in this way will, after polishing, of course, be only a few fractions of a millimeter thick, which will in no way spoil the touch screen; the screen remains as pliable as before. At least much better than after gluing the protective film.

As step-by-step instructions for restoring the oleophobic coating on your phone screen, we used the instructions indicated on the label of the product used. The only differences:

Cleaned the phone more thoroughly. The slightest traces of fingerprints and traces of grease were removed.
Using thin pieces of masking tape (painting tape because it is easy to peel off), we sealed the speaker, the camera hole, and any other vulnerable areas where the tape could get caught.
After applying the coating, it was polished with a silk cloth, approximately the same as is usually used for cleaning glasses.

We used this one as wax -

But from practice it became clear that others that you can buy will also be suitable. When comparing, pay attention to the indication of the thickness of the resulting film and the thickness of the coating. It is not indicated everywhere, but the thinner the better.

The result is the purest, moisture-repellent oleophobic coating, excellent response of the smartphone display, almost complete repellence of fat, an almost new phone without fingerprints!

Oleophobic coating is the essence of protection

A thin film with a thickness measured in nanometers repels grease from any surface. The invention belongs to three German scientists who officially patented the coating on July 20, 2005. It became widely available after Apple and other manufacturers appeared in the mass market. Unfortunately, the coating is not very durable - with active use it will wear off within six months.

Does yours have an oleophobic coating?

To install this for sure, drop a drop of water on the screen; if the liquid spreads unevenly across the display, there is no coating or it is worn out. A completely new coating easily repels water, and a drop, sliding across the screen, does not lose its shape and does not leave a mark. On the new coating, fingerprints do not remain or are barely noticeable. However, such protection is the prerogative of the middle and high price range.

How does the oleophobic coating wear out?

The coating wears off not only from constant contact with your fingers, but also as a result of friction against clothing. Everything is simple here - the more often you wipe the screen, the thinner the coating becomes.

By the way, the oleophobic coating is afraid of alcohol like fire, so don’t even think about wiping your display with alcohol-containing products - you’ll say goodbye to grease protection instantly.

Methods for restoring oleophobic coating

You can take the cheapest route and purchase protective glass or film with an oleophobic coating. You should not glue such a protective material onto a new one that has not yet worn out its oleophobic coating, otherwise you will subsequently peel off the coating along with the protective material.

You can take a dubious path and resort to “folk remedies,” which are a dime a dozen in Russia. But they all boil down to one thing - purchasing any water-repellent/dirt-repellent nano-liquid designed to protect car windows, and then applying it to the screen. Who knows, maybe this method of protecting the display is effective, but where is the guarantee that such products are non-toxic and will not cause problems later when in contact with the skin.

You can take the appropriate route and purchase a special Japanese-made Fusso SmartPhone liquid or its equivalent on eBay. The cost of a well-proven product varies between 1000 rubles per 3 ml. The liquid applies a new layer of oleophobic coating to the screen.

And finally, the fourth method. Expensive. This is a screen replacement at a service center, which is not entirely advisable, given that there is an effective way to restore the oleophobic coating described above.
