Air bubbles are the main problem when installing the screen protector. They occur when dust gets under the screen protector. In this article, you will learn how to remove air bubbles at home and avoid buying new safety glass.

To clean your screen protector, you will need stickers, which are included in most safety glasses. If there are no stickers, normal duct tape or paint tape will do. It is also recommended to wet clean and dust the room before the procedure; otherwise, there is a high probability of even more air bubbles forming.

3. Then use the stickers provided with the glass or tape. Stick the adhesive tape/sticker to the place where the bubble was, then peel it off. The essence of the procedure is that the dust will stick to the sticker. You should treat the back of the screen protector; the surface of the mobile device is also recommended to wipe with a tissue.

How to prevent air bubbles from forming under the screen protector

Air bubbles are caused by dust between the screen protector and the front of the mobile device. The presence of dust interferes with the tight fit of the glass, causing an air bubble to form. The main reason for this phenomenon is high dustiness inside the room. Therefore, the best way to prevent the formation of bubbles is to reduce dust in the air by wet cleaning.

It is also important to wash hands thoroughly and dry before installing the screen protector. Since the installation process uses your hands, grease or moisture on your fingers can also cause air bubbles under the screen protector.
