Computer cleaning involves the removal of dust, dirt, and debris from computer components to maintain their performance and extend their lifespan. Components that require cleaning include the monitor, keyboard, mouse, and internal parts such as fans and vents. Compressed air can be used to remove dust and debris from components, while microfiber cloths can be used to wipe down surfaces. It is important to avoid using harsh cleaning solutions or abrasive materials that can damage components. Regular computer cleaning can improve airflow and prevent overheating, reducing the risk of component failure and extending the lifespan of the computer.
