[Leica] [Q] How to clean a 21mm finder?

[Arne Helme <arne@acm.org>]

I have a few things to say about the 21mm black plastic finders.  (1)
they *look* cheap, but (2) they *are* expensive, and (3) dust builds
up on the inside of their main lens element (in mine at least).
Apparently there is sufficient space between the lens element and the
plastic housing to let dust in.  It's not that dust specks irritate
me, but after about a year of use the finder has become difficult to
use because of stray light created by an increasing amount of dust.

Thus, due to (1) I have the urge to break the thing open to clean it
but (2) has prevented me from doing it so far.  Has any of you
experience (or suggestions) with regard to cleaning the inside of
these finders?  Of course, I can leave it the way it is, but sooner or
later the dust will start irritating me...
