How do you clean a lens, INSIDE??

    I bought three digital cameras at a garage sale today.
    Turns out that the guy lived on a boat.

    The Oly D-300L and the Coolpix 990 are gonna be ok.
    But the Nikon Coolpix 4500 spent a little too much
    time on the boat. If you look in the lens, the surface is
    cloudy and there's white residue on the metal parts.

    Is there any hope of cleaning this thing and making it work?
    I've got nothing to lose.

    I'm afraid to power it up for fear of doing more damage.


    Ideas?
    Thanks, mike

  2. I have a CP4500, and am pretty sure that someone has posted (on the web) how
    to disassemble a CP4500 (or maybe the earlier CP995, 990 series) with a view
    to removing the IR filter. I didn't keep a record - suggest you try Google
    Groups, or the Nikon forum at www.dpreview.com

    Thanks, I found some references to disassembly, but no real info.
    I pulled out the trusty screwdriver and took apart the side with the
    lens. Looks like a snowstorm inside. I'm optimistic that the
    electronics can be saved. But the mechanical stuff may be another story.
    My original question remains: What can I use to clean lenses that will
    take off the white film of corrosion products without taking off the
    optical coatings?
    Won't do any good to spend a week fixing the electronics if
    the lenses are not recoverable.

    I took a Q-tip and alcohol to the inside of the front cover glass.
    Cleaned up nicely, I'm just afraid to try that on the lesnses without
    asking.

    While I have your attention, what would be the symptom showing in the
    picture if I did take the lenses down to bare glass?
