The proverbial ... You need to hang around the cosmetics counter more,
Gareth.
For removal of "debris" from the mirror, I used a Post-it note - folded to
give some stiffness, then dabbed on the offending layer of dust. No
dragging, no scratching, no residue. And no ethanol, that's for keeping in
the freezer for refreshment purposes only.

Subject: Re: [OM] Best way to clean OM-1N mirror
Oh I never would scrub any optical surface, I meant it in a generic
context :) ! Am I safe in assuming that the mirror is removed while
cleaning? Also is the mirror aluminized on the front or rear surface (I
assume its rear sufrace silvered)? That's something I've never actually
looked at but I assume it could affect the cleaning process somewhat.
By the way there is a lot of talk about Q-tips. What are they?
Special optical cleaners or the preverbial cotton bud?
All the best,
Gareth.
