Subject: [rollei_list] Cleaning Rolleinars
Just received the set of Rolleinars 1, 2, 3. Needless to
say they are not in the pristine condition as they appeared
in the photos. I'm wondering what is the best way to clean
them?
Thanks!

Same as any other lens, try any of the "streak free"
glass cleaners first. Use soft, lint free tissue such as
Kimwipes or Kodak Lens Tissue (if you can still get it). Wet
the tissue and drag it accross the lens then toss it and use
a fresh tissue for the next application. If the lens is
dusty use a hand air bulb to blow it off. Canned air works
but be careful not to use too much pressure. Another way is
to make a one-use brush from lens tissue by rolling it up
and tearing it, fold the two torn ends together and use the
feathered ends to brush off the dust. Use each brush _once_
onl and discard.
Some lenses have oil or greas on them, the best
solvent is either naphtha (Ronsonol lighter fluid is good
and leaves no residue) or acetone. Acetone is a standard
solvent for cleaning lens components in manufacture but can
dissolve many paints and plastics so must be used with care.
Never scrub a lens.
I am also not enthusiastic about micro-fiber cloths, the
problem with anything that is re-used is that it can pick up
particles of grit and cause scratching. Some of the newer
lens coatings are fairly hard but most of the older ones are
not and are quite vulnerable to scratching. Also, some types
of optical glass are rather soft and can be scratched by
cleaning that would not affect a window.
I don't know if any of the Rolleinars have air spaced
elements but in general lenses that do can develop a haze in
the sealed compartment. Mostly this haze comes off with
ordinary glass cleaner but getting access to the inside of a
lens cell can be difficult.
