If using immersion oil, always ensure the objectives are cleaned immediately after use. Make sure you choose the good-quality immersion oil, lens paper, lens cleaner, and know how to use it for how to use microscope immersion oil and clean oil lens, click here.
Objective, eyepieces and condenser can be removed for cleaning. However, do not use organic solvents that may damage the coating on the lens. Microscope lenses can be easily scratched and should be treated with great care. To remove dust, use an air blower can be found in a camera cleaning kit carefully without touching the lens. The sticky residue like oil stain or fingerprint can be removed with a special lens paper moistened with distilled water or lens cleaning solution and rubbed gently using a circular motion from the center to the edge.
You can wrap a piece of lens paper around the tip of a cotton swab to clean it as well. Never clean lenses with alcohol, ordinary tissues, cleaning paper, toilet paper, cotton wool or hand towels, which can scratch the lens surface. Never use sharp instruments or anything abrasive on the microscope lenses. Never touch the lenses with your fingers. Your body produces oil that smudges the glass. This oil can even etch the glass if left on too long.
Whether transporting or storing your microscope even stored in a cabinet , always keep your microscope covered. Because your microscope is a complicated optical instrument that includes several lenses, filters, mirrors, and condensers aligned in a closed system.
Any dust fallen in the light path will interfere with the quality of microscopic images ie. Especially, eye tubes need to be kept free of dust so do not store a microscope without the eyepieces. If eyepieces or objective lenses need to be changed, do it carefully and quickly in a clean room like how you handle the traditional film camera. If the microscope eyepieces must be removed, cover the tubes with caps or a plastic bag with a rubber band around the eye tube to prevent the internal optics from exposing to dust and fungi.
Always contact the store where you purchased the microscope and ask professional technicians to fix it. Make sure you store your microscope in a clean, dry space with good air ventilation.
Moisture may corrode the metal parts of your microscope and allow mold to grow inside the microscope. Salt air or damp can also cause damage to the equipment over time. Similarly, keep your microscope away from areas with potentially corrosive chemical fumes.
Such fumes can destroy lenses or corrode metal parts. Also, place your microscopes on a stable surface and avoid any consistent shake. After using your microscope, turn off the illuminator and wait for it to cool down before putting on the dust cover. Allowing the bulb to cool will extend its lifespan and avoid the unnecessary cost of expensive replacements. Ensure that the storage area does not expose the microscope to prolonged periods of direct sunlight. For an added layer of protection, store the covered microscope in a plastic tub with a lid on it and store the tub on a flat surface.
