Lens and filter cleaning
Do not let dust, fingerprints, etc. get on the lenses and filters. Dirt on the lenses, filters, etc. will adversely affect the view of
the image. If any of the lenses or filters gets dirty, clean it as described below.
Use a blower, etc. to blow away dust. If this is not sufficient to remove the dust, brush away with a soft brush or gently
wipe away with gauze.
To remove fingerprints or grease, use a piece of soft, clean cotton cloth, lens tissue, or gauze moistened with absolute
alcohol (ethyl alcohol or methyl alcohol). However, do not wipe twice with the same part of the cloth.
Use petroleum benzine to clean off immersion oil. Wiping with absolute alcohol (ethyl alcohol or methyl alcohol) will
complete cleaning.
If petroleum benzine is not available, use methyl alcohol. Note that the cleaning effectiveness of methyl alcohol is low
and it will be necessary to repeatedly wipe. (Normally, wiping three or four times is sufficient.)
Be sure to use petroleum benzine only for cleaning off immersion oil from objectives. Do not use it for cleaning
eyepiece tube entrance lenses, filters, etc.
Absolute alcohol and petroleum benzine are both highly flammable. Be careful when handling them, when around open
flames, or when turning the power switches ON and OFF.
Follow the instructions provided by the manufacturer when using absolute alcohol and petroleum benzine.

Cleaning painted components
Do not use organic solvents such as alcohol, ether or paint thinner on painted components, plastic components or printed
components. Doing so could result in discoloration or in peeling of the printed characters. For persistent dirt, dampen a
piece of gauze with neutral detergent and wipe lightly.

Storage
Store the instrument in a dry place where mold is not likely to form.
Store the objectives, eyepieces, filter cubes, etc. in a desiccator or similar container with a drying agent.
Protect the instrument from dust by covering it with the vinyl cover.
Before putting on the vinyl cover, turn off the power switch on the microscope and other equipment, and wait until the
lamphouse has cooled.
