Cleaning
- When cleaning lens, gently wipe with a microfibre cloth. When removing fingerprints, use rubbing
alcohol to wipe the surface.
- Do not use any solvents to clean the microscope, except for the lens. To clean the non-
glass parts, use a soft cloth without lint, moistened with a small amount of neutral detergent.
