Explanation:

You can try using a squeeze bulb or compressed air can to blow the dirt off the lens. Just make sure you don't use any spray cans with cleaners in them. Once you have blown the lens clean, gently wipe it using lens paper. Lens paper is a soft, lint-free tissue paper meant to be used for just such applications.

Answer:Blow all loose dust particles away with a dust blower.

■ Remove all water-soluble dirt with distilled water. If

this is not successful, repeat using diluted dishwashing

liquid.

Remove any remaining residue with a dry cotton swab,

but breathe on the surface first to generate a film of

moisture. Be careful not to spray droplets of saliva onto

the surface.

■ To remove oily dirt, first use diluted dishwashing liquid.

If the result is not satisfactory, repeat using a solvent

(Carl Zeiss Optical Cleaning Solution, or n-hexane).

■ Greasy dirt must always be removed with a solvent.

■ After cleaning, inspect the surface (see section „How to

Recognize Dirt“, page 5).

Place the objectives, eyepieces and cameras on a dust-free

surface (e.g., fresh aluminum foil). All other components

to be cleaned should be accessible in the best possible

way.

Dip the cotton swab or ITW Texwipe CleanTips® swab

into the cleaning solution and shake off excess liquid. An

excess of liquid in a cotton bud will flow over the rim of

the lens and attack the lens cement. This may cause the

cemented components to finally come apart.

The solvent should take up as much dirt as possible.

In order to increase the retention time of volatile organic

solvents in the cotton bud, some users chill the solvent

(-10°C to -20°C). Chilled solvents have a disadvantage,

though: Due to their low temperature, atmospheric moisture may condense on the lens surface and leave a residue.

A more suitable way to improve the retention time of a

solvent is to add isopropanol, for example
