5.2 Cleaning
Non-optical surfaces: The non-optical surfaces of the lens can be
cleaned with water, mild detergents, and a soft cloth.
Optical Surfaces: The optical surfaces of the lens should only be
cleaned when visible dirty. Care should be taken to avoid touching
the exposed lens faces. Skin acid left behind with fingerprints can
be damaging to coatings and lens substrates. First use a jet of air or
blow across the surface to remove any sand or abrasive particles
before cleaning. If oil, water spots, or fingerprints form on the
optical surfaces, clean as soon as possible using a soft cotton cloth
and mild neutral soap diluted with lukewarm distilled water (1 part
soap to 100 parts water), followed by reagent grade isopropyl
alcohol or acetone swab. Dust can be removed gently using alcohol
or acetone swab.
Note: Avoid swabs that incorporate plastic stems, as some plastics
will dissolve in alcohol or acetone.
