What to Watch Outfor when CleaningMicroscope Optics1. When starting to clean, don‘t forget to use a dust blowerfirst, except when liquids (such as immersion oil) have to beremoved.2. Never wipe lenses with dry swabs or tissue – this will causescratches!3. Don‘t use abrasive materials such as dry leather wipers, drylinen cloths or polystyrene sticks as recommended by somemanufacturers.4. Don‘t apply any solvents before trying distilled water,except when grease has to be removed. (A film of distilledwater can be created by breathing on the surface.)5. Don‘t use ethanol, diethyl ether or acetone for cleaningolder microscopes(e.g., the STANDARD line from Carl Zeiss Oberkochen,or the MIKROVAL and JENA-Microscopes 250 CF linesfrom Carl Zeiss Jena).6. Don‘t use any disposable cotton swabs (e.g., Q-Tip®)instead of the cotton or ITW Texwipe Clean Tips® swabsrecommended herein, as the former are not free fromcontaminations.7. Beginners should not use any of the occasionally recommendedmetal rods instead of the wooden (bamboo)sticks, as the front lenses may easily get damaged by theformer.8. Don‘t use any of the optical spray cans containing pressurizedliquid air. The pressurized air from these cans mayeasily leave a residue that is difficult to remove, if at all.9. Never use acids or ammonia to clean objective front lenses,which are sensitive to acid and alkaline vapors.10. Never try to clean internal optical surfaces, cameras oradapter optics.17
