When seeing fingerprints, stains or blurred streaks on the computer screen, many people often immediately take water to wipe the glasses for cleaning. However, according to technology experts, this is one of the most common mistakes that can damage the screen.
Using glass cleaning solution for the screen seems reasonable because both are surfaces that need to be cleaned and kept transparent. However, computer screens and lenses actually have completely different structures.
Eyeglasses are a solid surface, capable of resisting specialized cleaning chemicals. Meanwhile, most computer screens today, especially LCD screens, are made up of millions of pixels and many layers of surface protection.
Glass cleaning solutions often contain chemical ingredients that have strong cleaning capabilities to remove dirt and grease from the glass. When used on computer screens, these chemicals can damage the anti-glare, anti-reflective coating or other protective layers on the screen surface.
Not only affecting the outer coating, spraying glass cleaning solution directly onto the screen also poses a more serious risk.
Experts warn that the liquid may see through the screen bezel slots and penetrate inside the electronic component system. This can cause short circuits, causing dead pixel areas or irreparable black patches on the screen.
In many cases, the repair cost is even significantly higher than replacing another screen.
Instead of using glass cleaning solutions, users should choose a specialized soft microfiber cloth to wipe the screen.
For ordinary dirt, just wipe gently with a dry cloth is enough. If more stubborn stains appear, you can use a solution consisting of 50% water and 50% isopropyl alcohol (IPA) to support cleaning. It should be noted that only moisten the wipe and then clean the screen, absolutely do not spray the solution directly onto the device surface.
Experts also recommend choosing wipes that are suitable for each type of screen, especially OLED panels that have a more sensitive surface than conventional LCD screens.
