What is important to know before removing scratches from a smartphone screen.
Why do we see scratches
They have sharp edges that reflect light and make damage easily visible. That is why small abrasions are usually striking on an extinguished display, and when the backlight is turned on, they are hardly noticeable or not visible at all.
What scratches can be removed
A distinction should be made between the types of scratches. All tempered glass screens have a special oleophobic coating, thanks to which fewer prints are collected on it and fingers glide better. First of all, it is it that suffers: over time, a thin layer of spraying is erased from touching with hands, rubbing against clothes.
If you see small abrasions from a certain angle and they do not cling to your fingernail, then most likely these are not glass scratches, but an oleophobic coating. Fortunately, it can be restored.
Deeper lesions that are visible from any angle and can be clearly felt with the fingers may not be able to be removed completely. But they can also be made less noticeable by polishing.
Which methods work and which don’t
To get rid of a scratch, you need to fill it with something, smooth out sharp edges or cover it on top. There are not many ways to do this. In the first case, an oleophobic composition is used, which is able to clog shallow depressions. Smoothing is polishing with an abrasive paste. And to cover the screen to change the refraction of light and hide scratches, you can use a protective film or glass.
Toothpaste, baking soda , baby powder, vegetable oil and other tips that the Internet is full of do not work. And although there is a certain logic in them, the result is likely to be dubious. Paste, soda and dusting powder act as abrasives, and oil replaces oleophobic dusting. But what is the point of experimenting with improvised means if there are things specially designed for this?
What can be polished
Special polishing pastes and compounds are best suited. For example, GOI paste , well-known since the times of the USSR , was used for fine-tuning optics and processing jewelry. It is produced in the form of green bars, reminiscent of plasticine, and comes in different grain sizes: No. 1 is the finest, No. 2-4 – coarser.
Another option is cerium oxide powder . It is a specialized agent that is used for polishing car windows and in the production of glass products.
Also suitable are professional polishing pastes, which are used by craftsmen to treat paintwork in cars.
Will the display deteriorate from this?
Polishing has the greatest impact on the screen. After it, the oleophobic coating is guaranteed to be removed. Although it can be restored for a certain period of time and, if necessary, it is easy to repeat the procedure.
The sensor and display will not be damaged by polishing. If, of course, you are careful not to put pressure on the gadget as much as possible. This, by the way, is not necessary: such diligence will not affect the quality.
It is important to remember that if the screen protector is not made of glass, but of plastic, then it is better not to polish it or do it very carefully. The plastic can easily overheat, it will become cloudy and the display will be damaged.
How to remove scratches from a smartphone screen
1. Restore the oleophobic coating
As mentioned above, this option is suitable for minor scratches, as well as to return the screen to usability after polishing.
What is needed
- Oleophobic composition ;
- cling film or bag;
- microfiber cloth.
How to do
- Use rubbing alcohol and a microfiber cloth to thoroughly clean the screen to remove all dirt and degrease it.
- Wrap your finger in cling film, a bag, or other non-absorbent material.
- Apply a few drops of the composition to the screen and distribute it evenly with a prepared finger. Act quickly as the liquid evaporates instantly. You do not need to press and rub it into the display – just spread it over the surface.
- Do not use your smartphone for 8-12 hours to freeze the oleophobic film. Given this, it is most convenient to carry out the procedure before bedtime.
- Wipe off the rest of the composition with a dry microfiber cloth, and the smartphone can be used.
2. Stick on protective glass or film
Deeper scratches can be easily hidden by gluing glass or film to the screen . The thicker the protection, the deeper scratches it masks. Even a crack will not be visible under the massive glass.
What is needed
- Protective film or glass;
- liquid for cleaning displays or alcohol;
- microfiber napkin;
- stationery tape;
- plastic card or scraper.
How to do
- It is best to glue the protection in the bathroom a few minutes after taking a shower, when the dust is bound by the steam and settles on the floor.
- Place the glass or film on the right side of the screen, perfectly aligning the gaps around the perimeter and cutouts of the camera, speakers, and other openings.
- Gently stick two or three strips of narrow tape along the edge of the protection on one side so that it also goes into the smartphone and you get something like an opening book.
- “Open” the glass or film and thoroughly clean the screen from streaks and grease with a cloth moistened with liquid for cleaning displays or alcohol. Then wipe the surface dry with another tissue.
- To be on the safe side, collect possible dust particles from the display by gluing and peeling off a special sticker from the protection kit or, if it is not there, a piece of scotch tape.
- Lift the glass or film vertically, carefully remove the bottom protective layer and quickly lower it onto the smartphone. Using a napkin or card, disperse air bubbles from the center to the edges and remove the adhesive tape.
3. Polish the screen
If you do not want to hide scratches under protection, then polishing is the most effective option to completely remove or at least reduce abrasions.
What is needed
- GOI paste, cerium oxide or polishing paste;
- soft napkins;
- masking tape.
How to do
- Take masking tape and paste over the smartphone screen around the perimeter so that the polishing compound does not get on the case. Also cover ports, speaker openings, microphones, and other slots.
- Apply a small amount of the product to a napkin: rub it with GOI paste, drop a few drops of polishing compound or cerium oxide powder mixed with water to a slurry state.
- Wipe the screen surface with a tissue for several minutes with light circular motions without pressure.
- With a clean, slightly damp cloth, remove the remaining paste and evaluate the effect. Reapply the compound if necessary and carry out another polishing step.
- When you are satisfied with the result, clean the screen with a tissue and remove the masking tape. If desired, restore the oleophobic coating with a special compound.
