How to independently remove scratches from the screens of gadgets and household appliances

In the modern world, it is difficult to imagine your life without convenient gadgets - smartphones, tablets, etc. Even household appliances have screens and displays. However, in addition to convenience, all these devices have some subtleties. For example, the display may become covered with small scratches, which will spoil the appearance of the device. Of course, you can always go to a gadget repair center, but some people repair such damage at home, using available tools.

What screens for gadgets and equipment are made of

There are two main technologies for manufacturing modern screens: LCD and LED. Displays and screens LCD are liquid crystal panels that are equipped with modern gadgets (smartphones, tablets, TVs, etc.). LED (OLED) is a kind of LCD, but such screens are organic technologies. In addition, there is another technology - E-ink, which is theoretically also applicable to the manufacture of most devices, but it is more expensive, therefore it is rarely used. The durability of LED and LCD screens is individual for each piece of equipment, but on average - from 5,000 to 30,000 hours of continuous light.

Important: the lifespan of a gadget / technology and durability are not the same thing. If the screen has expired, this does not mean that it will stop working (just liquid crystals will stop "working" in full force). And vice versa - the screen may become unusable long before the expiration of the warranty period. This is most often the case.

How does screen damage occur during daily use?

During everyday use of the gadget, it is the screen that often suffers (mechanical damage). If we are talking about a smartphone, then the screen becomes covered with small scratches in contact with other surfaces. The screen of a TV, for example, can become scratched when wiped with a coarse cloth. The scale of damage also depends on the care in handling the gadget. This way your tablet will have a smoother screen for longer if it's packed in a protective case.

Special tools for removing scratches from screens

If the owner of the gadget / equipment turns to a repair shop, then special means can be used to eliminate mechanical damage: GOI (or Displex) paste, Turtle Wax, aluminum-potassium sulfate, etc.

Paste GOI

GOI (developed by the State Optical Institute) is a special paste that is used to polish the surface of various materials (plastic, glass, metal, etc.). It is created on the basis of trivalent chromium oxide. There are 4 types of this paste (according to the size of abrasive particles), thin GOI paste No. 1 is suitable for processing screens, and No. 2 for polishing plastic cases. For minor scratches, a soft cloth (such as flannel) is required. A small amount of the paste should be applied to this fabric and the "wounded" surface should be polished until visible damage disappears. You can buy GOI paste at any store that sells polishes (household polishes, auto parts, etc.).

I had to resort to using such a paste. There was a small block among the tools, but it was dry, so it was inconvenient to work with it. I went around several shops. I have met the paste "Goi", "GOE" and even "Goya". It turned out that these are all commercial names of GOI. They all have the same composition.

GOI paste can be sold in cans or bottles, in the form of bars and discs

Displex paste

Displex paste is an analogue of GOI. It is used according to the same technology and the same rules. It is convenient to use the "display" to handle not only screens (including glass), but also plastic. Minor damage must be polished until the scratch is no longer visible. To do this, you also need to use a soft cloth. Finding Displex paste will be a little more difficult, since it is made in Germany. But the majority of "repairmen" believe that "Displex" has a softer abrasive composition than that of GOI. The price for a tube of this paste with a volume of 5 g ranges from 480 to 550 rubles.

Displex Paste is only available in yellow or red tubes

Car polishes

Automotive polishes are often used to remove large scratches on screens or plastic parts. They can be liquid or paste. To treat the screen, for example, smartphones, Turtle Wax or 3M Scratch Removal polishes are sometimes used. The scratch treatment technology is the same as for GOI and Displex.

Automotive products can be more expensive than specialized pastes, making them convenient for car owners. You can buy such polishes in auto parts stores, goods for repairs, etc. The cost of a car polish is from 300 rubles.

You can use liquid or paste-like car polish to remove scratches on gadgets or appliances.

Aluminum-potassium sulfate

Potassium aluminum sulfate ("alum") is an inorganic salt that is used in the textile, cosmetic and other chemical industries. Purchase such a substance only at specialized outlets selling chemical reagents at a price of up to 1 US dollar (per 1 kg). Sulfate is a free-flowing substance, there are several ways to use it. For example, to convert this sulfate into a paste, 1 egg white is added to 1 teaspoon of the reagent. After heating to 65 ^° C, a piece of soft cloth is soaked in the solution, calcined in an oven at a temperature of 150 ^° C, and then this piece is dried for 2 days. If you carry out this procedure 3 times, the fabric will become a polishing material with abrasive properties.

This method is often used abroad, in Russia it is considered too time consuming and complicated

How to remove scratches from the screen using the tools at home

There are different ways to remove small and deep scratches on gadgets and equipment. To eliminate minor damage, they use available means that are similar in properties to GOI paste, but you can use it. And to deal with deep injuries, they often use "rough" methods (mechanical), for example, a grinding machine.

Fast ways to remove minor scratches

The fastest home remedies for scratches involve the following:

1. Soda. You can use a dampened sponge instead of a cloth. Dry baking soda can damage the screen even more, in addition, it can fall asleep in the speaker, charging socket, etc. - this will cause the gadget to malfunction.
2. Vegetable oil. Unlike other methods, wiping the damaged surface with oil (a cloth soaked in oil) gives only a temporary masking effect. After such processing of the screen, it should be wiped dry with a dry cloth.
3. Baby powder (talcum powder). As with baking soda, talcum powder should be applied to a damp cloth or sponge. Talc is not very effective in such cases, but its abrasive particles are small enough; they cannot cover a damaged screen with more scratches.
4. Toothpaste. A small amount of the paste is applied to a cotton ball or cotton pad, and the scratch is treated in a circular motion. After work, remove the remaining toothpaste with a clean dry cloth.
5. Lipstick. The lipstick stick can be used as a "light" version of GOI paste, but it only fights very small scratches. In this case, it is important to use only non-persistent types of lipstick. This method can be used to smooth plastic surfaces.

Also, GOI paste can be used as an improvised tool

Last year I scratched the tablet display. The repair shop advised me to replace it completely, but the tablet was new, so I decided to look for alternative solutions. In another workshop, the scratch was reduced with the help of polish, and to completely eliminate visible residues of the scratch, it was advised to buy a protective film. They also told me how polishes remove those scratches. If you look at the scratch through a magnifying glass, you will notice that it looks like a ravine. Abrasive particles in the composition of various products seem to erase the edges of this ravine, smoothing out the scratch itself. And mild agents (like oil and lipstick) also fill the deepest part of the damage.

Methods for removing deep damage

Deep scratches can only be dealt with by strong mechanical methods:

1. Sandpaper (with fine abrasive). Sandpaper is able to completely erase a scratch. This method can make the gadget unaesthetic, so it is often used to deal with deep scratches on the screens of old gadgets (when no harm can be done) or plastic parts. This is one of the most unsafe ways.
2. Drill or sander with special felt attachments. They are used to enhance the effect of the use of pastes, talc, oils and other "chemical" agents. The use of this method is possible only in a professional workshop; it is not recommended to use this method on your own.

You can fight small scratches on your own, and it is better to entrust the elimination of deep damage to professionals

Measures to prevent scratches

In order not to have to eliminate damage on the screen, it is better to prevent their appearance. To do this, gadgets need care:

• it is recommended to store the gadget in a protective case (if the gadget falls down, it may still break, the case will only protect against scratches);
• you can pre-stick a protective film (or protective glass) on the device screen, but not all gadget models have such devices;
• The silicone bumper will help protect the plastic parts, but if it falls on the screen, the glass can still be damaged.

Reviews on the use of various methods of removing scratches

There are several ways to fix scratches on the screen, but they all involve an abrasive effect. Experienced repairmen use special polishing agents, and at home, you can use available tools. Small scratches can be removed independently and without harm to the gadget, and it is better to entrust deep damage to a professional.
