Than you can fill the cracks on the display. The screen on the touchscreen phone is cracked - what to do? Using toothpaste

Unfortunately, on the road, not a single motorist is immune from minor, but annoying troubles. Even with very careful driving, a stone can fly out from under the wheels of an oncoming car and damage the windshield of your car. In such a situation, the owner of the damaged car is faced with the question of how to remove the crack on the windshield? Go to a car service or try to fix the problem yourself? Today we will tell you how to fix a crack on the windshield with your own hands and not overpay for expensive repairs, but this, of course, if the glass is not completely crumbled and cracked like a cobweb.

Damage types

You should immediately clarify what mechanical damage can be repaired on your own. These types of damage include:

Chips. They need to be eliminated immediately so that branching does not go.
Simple cracks formed as a result of a sharp and constant temperature drop. This can happen if the car is not warmed up properly and the temperature conditions are not observed inside and outside the passenger compartment.
Chipped. The reason for their appearance is mechanical impact.
Branched cracks. Unlike simple cracks, such damage is difficult to remove. Sometimes an untimely solution of the problem can lead not only to the appearance of deep branched cracks, but also to a complete replacement of the windshield.

Important! Any mechanical damage can lead to the complete unusability of the glass, if not removed in time.

What factors lead to cracking?

Automotive glass can be mechanically damaged by being hit by a foreign object. However, glass cracks can also occur for other reasons. Here are just a few possible reasons damage:

Sharp temperature fluctuations. This is one of the main reasons. If a stream of cooled air hits a heated glass, and vice versa, when a hot stream of air is supplied to a cooled glass, a crack may appear. Often, damage is recorded in the place where the wiper is heated.
Poor quality glass. A gross violation of production technology can lead to damage to the glass, which simply cannot withstand too much stress.
Severe deformation of the vehicle body. In this case, the crack does not form immediately, but gradually.
Unnoticed chips that lead to glass breakage.

How can you avoid the problem?

There are various proposals on the market for windshield protection. One of the most popular options is a sticker of a protective film that protects an expensive car part from mechanical stress.

In addition, the car owner himself should adhere to the following rules for operating the car:

Check the degree of heating of the windshield and rear window. Do not blow cold air onto hot glass.
Replace the part only with a quality version.
Inspect your vehicle regularly for chips and other defects. If damage is found, fix it securely with a special sealant to prevent the crack from branching.

Important! If on the way you "caught" a pebble, then, first of all, it is necessary to prevent the ingress of dust and dirt into the crack. Cover the damage with tape along its entire length. This not only protects the crack from further deformation, but also facilitates the final clean-up later. Otherwise, the dirt accumulated at the bottom of the chip will be visible inside the glass after repair.

Can a crack on a windshield be repaired?

There is an unequivocal answer to this question - it is not only possible, but also necessary. Many drivers are in no hurry to solve the problem and drive with damaged glass. But with such a ride, other problems arise:

Visibility on the road decreases.
The crack glares in the sun, distracting the driver.
The level of driving safety is reduced.
Excessive loads and pressure have a destructive effect on cracks. And this can lead to serious consequences and a problem that only experienced craftsmen can solve.

In order not to bring the matter to an expensive repair or replacement of a part, we suggest that you familiarize yourself with the repair process and remove the crack on the glass yourself, in a timely manner. Moreover, the professional services of most car services are not designed to eliminate one single problem.

How to remove a crack on the glass?

The essence of the repair is to fill the damage with a special photopolymer composition to the full depth. The glue will do two things:

Will connect the edges of the crack and prevent it from growing.
Will make the damage almost invisible, due to the fact that the refractive index of the product is approximately equal to the refractive index of the glass.

So for self repair damage, you will need the following materials and equipment:

Photopolymer glue. The product is designed specifically for automotive and other glass. The solidification of the polymer occurs due to the action of directional ultraviolet radiation. Curing time: 15 minutes with UV lamp, 45 minutes with natural drying.
UV lamp.
Plastic (disposable) or metal (reusable) glue injector.
Applicators for attaching the injector to the glass.
Electric drill with diamond drill. It will help relieve internal stress in the glass and prevent further deformation.
Vacuum pump. A tool is needed to remove air from the crack.
Mirror for defining the boundaries of the defect.
Scrubber for cleaning damaged surfaces.
Cleaning liquid and wipes to remove moisture and dirt.
Alcohol (medical or isopropyl alcohol) for degreasing the repair site.

Important! Instead of a drill, you can use a dental bur, which is sold at Medtekhnika. Use it carefully so as not to drill through the glass.

Having prepared the necessary set of tools and materials, proceed with the repair, guided by the following instructions.

Step-by-step instructions for repairing cracked glass:

Thoroughly clean the glass and the edges of the crack from dirt. Use a degreaser and a pump for this purpose. Blow out all road dust and dirt from the damage, degrease the entire repair area. The quality of the entire repair process depends on how well the preparatory measures are carried out.
Release the tension on the glass. This must be done so that in the process of further measures the scale of damage does not increase. Perform this procedure with a drill as follows:
1. At a distance of 2 mm from the crack, drill a through hole towards the expansion of the damage.
2. Bring the crack to the hole with slight pressure. As a result, the crack will reach the drilled hole and will not go further.
Scrub the edges and area of damage with a scriber.
Treat the prepared area with napkins dipped in a special cleaning liquid. You can degrease the surface with alcohol.
Allow the damaged area to dry out.
Prepare polymer glue according to the instructions.
Install the injection support (bridge). So that the bridge is securely fixed on the glass, grease the suction cup with Vaseline and install so that it is located directly over the damage.
Prepare the injector for use. For this:
1. Remove the oil seal.
2. Pull the piston down.
3. Put a few drops of glue into the injector.
4. Lift the adhesive up to the top of the cylinder with the piston.
5. Place the adhesive injector onto the bridge using the applicators. Make sure the center of the injector is aligned with the center of the crack.
Raise the plunger and let it sit for 1.5 minutes to allow the glue to completely fill the damage.
After filling the entire crack with glue, stop pumping. Remove the injector and axle.
Place a UV lamp over the crack for 15 minutes.
After the glue dries, remove any residue from the glass using a mounting knife blade.
Polish the repaired surface with a soft cloth and polishing paste.

The renovation is completed. Subject to the entire sequence of measures, the crack will become invisible.

You can use a special kit for the introduction of photopolymer glue. It is produced by many manufacturers. The set consists of glue and accessories. When buying a product, give preference to world famous brands - Done Deal, Permatex, Abro.
It is most convenient to observe the process of pumping glue from the interior of the car, illuminating from the side with a flashlight or a portable lamp.
Curing UV lamps for home use are excellent for curing the adhesive. If you have such a device, then use it. You can wait until the glue is completely dry and naturally... But this process can take up to 10 hours.
After removing the glue injector and applicator, apply a clear finishing foil to secure the product and lay it flat on the glass surface. Lay the plastic from the center out to the outside to prevent air bubbles from forming underneath. Smooth out the film with a flat object. You can remove the film after the glue dries with a plastic scraper or a wooden plate.

Glass surrounds us everywhere: windows, doors, dishes, transport and more. Cracks often form on the glass, so you need to know how to act in this situation. If the crack is huge, with a wide gap, then you need to contact the professionals in their field, if it is insignificant, then you can cope with the problem on your own. You can glue the crack on the glass yourself, the main thing is to use a proven method.

Attention, only TODAY!

According to statistics, appearing on the screen as a result of not too careful handling mobile gadgets cracks are the most common reason for contacting repair shops. And this is not surprising, because it is the display that is the notorious Achilles' heel for any, even the most expensive and eminent mobile phone. What to do if on touch phone cracked screen let's sort it out together.

What to do if the phone screen is cracked?

So, there is a problem - after the fall, cracks appeared on the screen of the mobile phone. How to act in this situation and how dangerous are they both for the phone itself and for its owner? It all depends on the degree of damage received. For example, if there are one or two cracks, and they do not interfere normal work a mobile gadget, it is quite possible to do with half measures - stick a protective film or glass over the screen. In this form, the phone will be able to work for a long time, and dust and moisture will not be able to get into it through the cracks. But if the screen is covered with craquelure from the smallest cracks, then you cannot do without a visit to the repair shop. Fully restore performance touch screen is possible only if it is replaced using special equipment. At the same time, you need to be prepared for the fact that replacing a cracked screen can result in expenses equivalent to half the cost of a new mobile phone. Therefore, in some cases it makes sense to think about replacing a broken gadget with a new one.

Is a cracked phone screen harmful?

Mobile technologies appeared not so long ago, but immediately overgrown with many myths and speculations regarding the harmful effects on the human body. In particular, one can often hear the opinion that cracked screen turns the phone into a time bomb. But in fact, the only harm it can hypothetically cause is to scratch the wearer's skin during a conversation.

If your gadget does not have a protective glass, and you accidentally made a scratch by negligence. Don't despair, we have compiled a few life hacks on how to remove scratches from your phone or tablet screen. There are many effective tools for this, among which there are both the simplest and most widely available and technologically complex ones.

Basic ways to remove scratches

Glass and plastic displays are prone to polishing (we'll look at how to polish a screen using specific methods below). The same can be said about protective glasses of lenses of cameras of mobile devices.

The choice of how to polish the screen or camera depends on the depth of the scratches and the total number of scratches.

Conventionally, methods for removing scratches from a phone can be divided into 2 groups:

1 Chemical... Moreover, they can be additionally classified:

On those that involve the use of publicly available tools that almost every homeowner has:

toothpaste;
soda;
vegetable oil.

And those that involve the acquisition of specialized (but at the same time widespread) chemical reagents and agents household chemicals, namely:

baby powder (talcum powder);
GOI pastes and its analogues (for example, Displex);
car polishes;
potassium sulfate.

2 Mechanical... They involve the use of:

sandpaper;
drill or grinder.

Let's study in more detail how to remove scratches from the camera on the phone or from the screen of a mobile device using the above methods.

Attention! You decide at your own peril and risk whether or not to use the methods described in the article. We cannot be held liable for possible damage to devices resulting from the use of the considered methods of cleaning displays and cameras of mobile devices.

Screen recovery with improvised means

You can remove minor scratches on a phone camera or gadget display using the most affordable means at home. It is expected that such products will have the least effect on the surface (can be removed effectively - small and small scratches).

It is about the application:

toothpaste;
soda;
vegetable oil.

We apply toothpaste

A small amount must be applied to the display or protective glass the camera lens with a cotton pad. Then in a circular motion (if scratches are observed over a large area) or back and forth movements with light pressure, you need to process the display, "erasing" the existing minor damage.

It is best to use the classic mint paste.

Fig. 1. We clean the device with paste.

Using baking soda

If toothpaste doesn't work, then another commonly available remedy is baking soda. The technology for cleaning the screen of a tablet or smartphone will be similar here, but instead of a cotton pad, it makes sense to try a foam sponge or soft matter.

Important! Soda should be slightly moistened before use. Dry powder can damage the smartphone screen, fall asleep through the cracks in the case and interfere with the operation of the device.

Rice. 2. "Soda" effect.

The advantage of baking soda is that it works a little harder on the surface of the screen than the paste, and therefore allows you to clean deeper scratches from the screen.

We use vegetable oil

Another remedy that is almost always at hand at home is ordinary vegetable oil. It does not have an abrasive effect like paste or soda, but it helps to effectively get rid of small scratches on the display glass.

It is necessary to apply literally a few drops of the product to the screen of the mobile phone, and then rub it with light movements on the damaged area of the display.

Important! The most important thing is not to overflow the oil - if it gets inside the device, it will be extremely difficult to remove it.

The hozmag will help

If removing scratches using the handy tools discussed above did not help, you may have to pay a visit to the local store to buy the following chemicals:

baby powder or talcum powder;
GOI paste or its analogs;
car polish;
aluminum potassium sulfate.

We use baby powder or talcum powder

Among users of mobile gadgets, there is an opinion that baby powder is cheap and cheerful, however, the effectiveness of its use is confirmed by practice. The main feature of the powder is that it involves a method of polishing, on the one hand, rather hard (since the powder contains solid particles), on the other hand, it allows avoiding the appearance of concomitant damage (since the particles of the powder are very small and there are no ways to cause a noticeable scratch).

Using GOI or Displex paste

These funds are specialized. They polish glass and plastic equally well. At the same time, in order to remove scratches from the smartphone camera, it is considered more effective to use GOI paste, and to clean the display - Displex.

Rice. 3. Displex - optimal for touch screens.

Application of car polishes

Products similar to GOI and Displex paste are car polishes. Among the popular brands of such products used to clean displays from scratches are Turtle Wax, 3M Scratch Removal. Car polishes are among the best for removing deep scratches from displays.

The mechanism of application of the above means - GOI pastes, Displex, polishes, is the same. Apply a small amount to a soft cloth, then polish the surface.

Note that the use of the above polishes may require the purchase of additional specialized products - for example, car wipes.

Uses of aluminum potassium sulfate and egg white

Among the exotic "chemical" methods of removing scratches from screens used by enthusiasts in the field of mobile electronics, the use of a mixture of these substances can be distinguished.

Rice. 4. The main thing is not to "sour" the screen.

Potassium aluminum sulfate (also referred to as "potassium alum") is an inorganic substance used in the leather industry as a tannin, in the textile industry, in the cosmetic industry. You can buy it at a chemical reagent store, including an online store (for example, https://lenreactiv-shop.ru).

You need to take 1 egg white and 1 teaspoon of aluminum-potassium sulfate. Then - mix them in a small container, pour into an aluminum cup (plate) and heat up to 65 degrees. Then you need to dip a piece of microfiber in the solution, then dry it in the oven, which is heated to 150 degrees (while putting it on aluminum foil).

Then - cool the microfiber by dropping it into water, then leave it to dry for 2 days at room temperature.

The whole procedure must be repeated 3 times. Using a piece of cloth treated with the indicated chemicals, rub the damaged surface of the mobile device. Remove minor scratches and damage.

The advantage of this method is that there is no need to use additional chemicals.

Let us now study how to remove scratches from a tablet or a similar device using mechanical methods.

Mechanical means

In advanced cases - if there are deep scratches or if the phone could not be protected from chips on the screen, it is advisable to use "heavy artillery" in the form of mechanical methods of removing damage from the display (note right away that they are not suitable for cleaning the camera). It is about the application:

sandpaper;
drill, grinder.

Remove scratches with sandpaper

The purpose of its application is to gradually erase the damaged surface to a depth corresponding to the depth of the scratch. As a result, the scratch simply ceases to exist.

Another question is whether the screen, thoroughly processed with sandpaper, will look aesthetically pleasing. It is clear that if, for example, an iPhone is scratched, it is not at all handy to remove scratches in this way. But if you need to bring the old gadget into a more or less "marketable form" - the method will come in handy.

Rice. 4. Is the method tough, but fair?

We use a drill (with a felt roller), a sander (with special attachments)

The main function of such devices is to multiply the effect of using the "chemical" tools discussed above by automating polishing. If a user who has tried manual polishing has failed, and how to remove scratches, he does not know - it makes sense to use the appropriate auxiliary devices.

Working at hundreds of revolutions per minute, a drill or grinder can provide incomparable results compared to manual methods.

Summarize

Thus, there are many ways to "renovate" the screen of a mobile device from scratches. Let's try now to display the main features of their application in a small table.

Method for removing scratches from a phone (mobile device)	Features (what to look for)
Polishing with paste	Mint paste is needed, preferably one color
Soda polishing	Moisten baking soda with water
Vegetable oil treatment	The main thing is not to overfill (otherwise the drops will get inside the device, and it will be extremely difficult to remove them)
Application of baby powder, talcum powder	Perfect solution for removing light scratches
Polishing with GOI paste	Allows you to clean the camera on your phone in the most efficient way
Displex Paste Application	Optimized for cleaning displays
Application of car polishes	May require the use of a special tissue rubbing tool

So, we have learned how to get rid of scratches on your phone screen. Both the simplest household substances - vegetable oil, soda, baby powder, and more complex types of household chemicals and reagents (such as a substance based on potassium sulfate) can be effectively used to remove scratches from both displays and protective glasses of cameras on mobile gadgets.

At the same time, one must remember that prevention is always better than “cure”. Per mobile device need care. Careful storage of the device must be ensured. So, nice case will protect the case, and a special protective film helps keep the display safe and sound.

Any barely visible scratch should be removed immediately. We have studied in detail how to remove a scratch on a phone screen - the most affordable means can be used for this.
