During installation or after some time of use, the tempered glass screen protector becomes clogged. Dust particles under the protective coating or accumulated debris on the edges do not affect the protective properties, but spoil the appearance. The instructions in this article will help you to clean the back side of the screen protector.

How to clean the adhesive side of the tempered glass

In most cases, it is necessary to partially or completely remove the screen protector for cleaning. Moreover, it will be possible to clean only the glass correctly. The protective film will not re-stick or the edges will not stick after installation. The same problem is with hydrogel films. Cleaning is possible, but in most cases it will not be possible to reuse the screen protector.

Instruction

1. Collect the necessary cleaning tools. You will need stickers or stationery tape, lint-free napkins and alcohol or disposable napkins soaked in alcohol, a dry napkin and a wooden toothpick. You may also need a gel to restore the adhesive base of the coating.

2. Prepare a place for cleaning. It is important to exclude the dust content in the air, otherwise, it will not be possible to clean the screen protector.

3. Degrease your hands with an antiseptic or washing with soap.

4. Use a wooden toothpick or a sharpened match to lift the tempered glass screen protector.

9. To remove dust particles, use stickers or tape. Press down the sticker, then slowly peel off the sticker. Do this several times until the coating is cleaned.

10. If it was not possible to clean the garbage accumulated on the edges with a sticker, use a second alcohol napkin.

In particularly difficult cases, when the glass has fallen to the floor and got dirty before installation, it may be necessary to wash the glass under running water. In this case, you will have to hold the glass in the palm of your hand with one hand and wash the adhesive side with the other.

When the cleaning of the screen protector is completed, it is necessary to prepare the smartphone for the installation of a screen protector.

  1. Degrease the phone screen with an alcohol napkin.
  2. Wipe off the remaining moisture and stains with a dry cloth.
  3. Attach the screen protector to the smartphone screen.

If the connection is not strong at the edges or in a certain area, then smear such areas with a gel that restores the adhesive coating and wipe off the remnants with a napkin. Such a liquid will fill the formed air space and exclude light areas at the edges.

1. Apply a little liquid in places where the glass is not tightly connected.

In cases where the adhesive layer is severely damaged, an adhesive liquid may be needed for fastening, which hardens under ultraviolet radiation.

It is necessary to apply UV gel to the screen surface, then apply a screen protector and evenly distribute the liquid over the entire area of the screen. Collect the remnants of the leaked gel with a napkin.

An ultraviolet lamp is suitable for drying and solidifying UV gel. If there is no lamp, it is enough to leave the phone for 2-3 minutes under direct sunlight. It is worth considering that the double-glazed window delays some UV radiation and increases the drying time. In cloudy weather, the drying time will increase significantly, or the gel will not dry completely.

Why is my screen protector so dirty?

On the one hand, you are constantly touching the screen of your phone, how can it not be dirty? On the other hand, there is a way to make the screen look better. You can use an oleophobic coating or liquid glass, which makes grease and dirt less likely to stick to the screen. When using tempered glass, you can apply a liquid film with an oleophobic effect on top, which will repel dirt. It is not recommended to apply a liquid film to ordinary glass due to the weak oleophobic effect. The liquid film should only be applied to the glass.
