How to properly clean a TV and monitor screen

Cleaning dust and dirt from your TV screen or monitor is a straightforward task. Screens naturally attract dust due to the presence of electric fields. The internal circuits of the monitor create an environment that causes tiny dust particles to become charged and settle on the surface. Over time, this leads to the accumulation of a dust layer. While this dust may be unnoticeable when the display is on, it becomes very visible on the black surface when the display is turned off.

Which Cleaning Agents Can Be Used

Modern TVs manufactured after 2000 typically feature LCD or LED screens, which are made of plastic that can be sensitive to harsh chemicals. Therefore, it’s not recommended to use cleaning products that contain alcohol or other chemical components designed for cleaning stainless steel or hard surfaces on these screens.

Additionally, avoid using window cleaners; while glass is generally resistant to most chemicals, plastic is not. Using such products can leave white stains that are difficult, if not impossible, to remove.

How to Clean Your TV, Laptop, and Monitor Screen

1. Turn off and unplug the device. Before cleaning, disconnect your TV or monitor from the power source. If you’re cleaning a laptop screen, turn off the device completely. This ensures safety and makes dust and smudges more visible.
2. Use a soft, microfiber cloth. These cloths are ideal as they do not leave lint or scratches on the screen. Avoid using rough fabrics or paper towels, as they can cause scratches or leave behind small fibers.
3. Start with dry cleaning. Gently wipe the screen using light, sweeping motions. Begin at the edges near the frame and gradually move toward the center. This method helps prevent dust buildup where the screen meets the frame and allows you to remove particles without smearing them across the display.
4. Use a damp cloth for stubborn dirt. If dry cleaning is not enough, slightly dampen the microfiber cloth with a specialized screen cleaner—never spray liquid directly onto the screen. This prevents moisture from seeping under the bezel, where electrical components and, in EDGE-lit displays, the backlight lines are located. Wipe the screen gently, avoiding excessive pressure.
5. Wipe away any remaining moisture. If moisture remains on the screen after damp cleaning, use a dry cloth to remove it. For small screens, the dry part of the same microfiber cloth is usually enough. However, if you’re cleaning a large TV, it’s best to use two separate cloths—one for damp cleaning and another for drying.

Important Precautions

• Never use water or soap-based solutions. Water is a strong conductor of electricity and can linger under the bezel, creating a risk of damage. Soap, on the other hand, is difficult to remove completely and may leave residue on the screen. Using these substances can do more harm than good.

Cleaning OLED TVs

LG’s OLED screens are designed to be extremely thin, essentially consisting of a delicate panel attached to the TV’s base. The screen is secured by a frame, making it crucial to avoid applying excessive pressure, especially around the edges. While the display itself is flexible, applying too much force can compromise its integrity. Additionally, be careful not to let any cleaning solution seep into the edges, as it may react with the adhesive used to secure the screen.

Samsung’s OLED screens, on the other hand, are more rigid due to their unique manufacturing process. To improve heat dissipation, the display is bonded to a thin layer of metal foil, which helps manage excess heat.
