How clean microscope inside?

To clean the inside of a microscope, first ensure it is unplugged and safely stored. Use a soft, lint-free cloth or lens paper to gently wipe the optical components, such as the eyepiece and objective lenses, with a suitable lens cleaner. For internal parts, like mirrors or light sources, use compressed air to remove dust and debris without touching the surfaces. Avoid using harsh chemicals or scrubbing too hard, as this can damage delicate components.
