    Dear All,

    I'm new to all this photography stuff and was wondering if someone could
    advise me. I noticed that I have got some dust/hair(?) on the mirror inside
    the camera, I guess when changing the lens. I've tried using a blow brush
    but it just seems to get worse. What is the best way to clean the mirror and
    focusing screen. Any help will be greatly received. Thanks in advance.

    Best way, compressed air in a can, holding the camera body so the
    mirror points down and the air shoots up.

    Photo stores and computer stores both sell it.

    Don't touch the mirror with your finger and don't use any cleaning
    solution. For recalcitrant dust, fog the mirror with your breath,
    gently rub the mirror with a piece of lens cleaning paper or a lens

    Can I just add a wee bit to this, don't use ANY lens cleaning fluids or
    detergents when cleaning camera glass, they can damage the special coatings
    on the glass.
    If the compressed air doesnt work , have the camera cleaned professionally,
    the only time fingers should be inside a camera, is to load or unload a
    film, and even then be very careful, a slight slip can easily destroy a
    shutter curtain.

    P.S Apparently cross-posting to multiple newsgroups is a hanging offence,
    I would strongly advise a swift apology to the groups you posted to, before
    a lynch mob turns up at your door, some people just hang around newsgroups
    waiting to pounce on newbies, and god forbid you should be caught "top
    posting" you may never have used newsgroups before, but the "law" says you
    must be fully aware of how it all works... from birth, no excuses.

    Using compessed air on a mirror is a great way to screw it up. They are a
    bit fragile. A small brush and gentle wiping (NO pressure) is better. It is
    best to leave the mirror alone. The focusing screen can be cleaned with
    canned air. Or a brush or even a cotton swab. Some of course are
    removable/interchangeable making cleaning pretty easy.

    That is correct, do NOT use compressed air on the mirror.

    Is that not what he said???, You contradicted your self there bud, if it can
    damage a mirror and the focus screen is as close to the mirror as it is,
    then in your view, the air from the cleaning of the focus screen would
    certainly "damage" the mirror. I am certain the guy isnt stupid and knows
    that he donesnt mean compressed air from a car workshop. I would not use a
    cotton swap as this can leave traces of cotton on the glass and allow it to
    work itself into the camera mechanisms. Lint free all the way. If the guy is
    new to camera repair and cleaning , then the worst thing you can do, is tell
    him to REMOVE the focus screen to clean it.
    Only remove the focus screen if you know what you are doing, I am sure if a
    mirror can be damaged by air, then it can be damaged by sticking your
    fingers or tools into the camera to remove a focus screen.
    Sorry if this sounds nasty, it isnt meant to be. just dont want the guy
    screwing up his pride and joy.

    Oh, and , see my other post, regarding cross posting.

  7. I have used a mixture of ethylene alcohol and ether (50% + 50%) on a very
    soft lense paper. Not rubbing, just tuching. Rather lot of the fluid.
    It worked very fine on my surface mirrow, but I give no guarnties it will on
    Compressed air doesn't not help if the mirrow id greasy. It only removes dry

    Bye the way, the same mixture is perfect for cleaning lenses as long as you
    don't get it inside the lens - the lens cement in coumpound lenses can be

    never been a problem,
    and camera vendor suggests it.

    just don't let the liquid spray onto the sensor.
    this happens if you shake the can.

    do what I do all the time.
    canned air blows the dust of the mirror and the sensor.
    never a problem.
