Screen cleaning refers to the process of removing dirt, dust, and smudges from the surfaces of electronic displays, such as those found on smartphones, tablets, and computer monitors. Proper cleaning helps maintain visibility and prolongs the lifespan of the device. To clean a screen effectively, use a microfiber cloth slightly dampened with water or a specialized screen cleaner. Avoid using paper towels or rough fabrics, as they can scratch the surface. It's important to turn off the device before cleaning to prevent damage and ensure a thorough job.
