<human>:  How can I safely clean a laptop screen?
<bot>: To safely clean a laptop screen, start by turning off the laptop. Use a microfiber cloth and avoid using any cleaners or detergents, as these can cause damage to the screen. Gently wipe the screen in a circular motion, taking care not to press too hard. For any tough spots or smudges, mix up a solution of at least 50% water and 50% isopropyl alcohol and dampen the cloth with the solution. Wipe the screen with the damp cloth and then use a dry cloth to remove any excess moisture.
