– Do not use organic solvents (e.g. alcohol, ether, acetone, xylol or other dilutions) to clean
lacquered parts or plastic parts!
– Disassemble optical elements (e.g. objective, eyepiece, etc) before cleaning.
– Blow away loose dust from the lens surfaces first.
– Use high quality lens cleaning towels or soft cloth and moisten it with a little bit of pure alcohol
(available in a drug store). Wipe the lens surface with it.
– Pull a dust protection cover* over the microscope and store it in a closed container at a dry and
mould-free place. Store the microscope and the accessories in the relevant containers when they
are not used for a longer time. It is recommended to store also objectives and eyepieces in closed
containers with desiccant.
