To clean a TV screen, you should use a soft, clean, lint-free, dry cloth. It is recommended to use a microfiber cloth for general cleaning of the frame and screen of your TV. Avoid using any type of window cleaner, soap, scouring powder, or any cleanser with solvents such as alcohol, benzene, ammonia, or paint thinner. Also, never use abrasive pads or paper towels, as they can scratch the screen or strip the anti-glare coating off the screen and cause permanent damage. If you need to remove stubborn stains, you can try using a solution of very mild dish soap highly diluted with water, applied to the cloth. Its important to never spray cleaner directly onto the screen, as this could damage the inner workings of the TV. Additionally, its recommended to clean the TV screen weekly to keep dust, film, and fingerprints from building up and becoming harder to remove.
