    Default Eyepiece cleaning question after Katrina



    Everything we owned was ruined by Hurricane Katrina. My eyepieces were in
    an eyepiece case that I thought was waterproof -- it was not. The case
    leaked and salt water wet the foam and the eyepieces. The eyepiece now
    suffer from:
    -- rust and pitting from salt water on all metal parts
    -- all glass is coated with a thin dull film of something, probably salt and
    junk from the water

    What can I do to clean the eyepieces? Or should I try? Insurance company
    reimbursed full price for all my eyepieces -- maybe I should just toss the
    old ones and buy new ones.

    By the way, anyone know of a truly waterproof case?

    If you don't mind, you could send them to me and I could see if I can clean
    them up for useage again. I've worked on a few camera lens that have been
    fished out of water and while maybe now 100% as they used to be, they where
    useable afterwards. As I live out in the High Mojave Desert, they would be
    far from any flooding and I use my model making tools for stuff like that.

    No charge either other than postage.

    Or, if the OP were to decide to just toss them, he could (idea the
    first) instead donate them to a good cause (like Starlord's sidewalk
    astronomy.)
    (Idea the second) put them on Astromart as described - lots of people
    would love to get a bunch of lens and parts to play with (and maybe even
    clean up.)
    (Idea the third - probably the OP's idea the first) disassemble them
    (keep track of what goes where; see recent post) and use one or more of
    the vast number of cleaning ideas scattered around the web; my idea
    would be to sock them in distilled water, then in pure alcohol (to dry
    them,) then reassemble them an see what you've got.

    As long as the lens are not glued together, the best way to get rid of the
    salts and crud is to use luck warm water, either soaking and then changing
    water offen or a in a basket under running water. Then a chemial bath to
    remove anything the water doesn't take off that got on the glass. Then a
    very light buffing with a camera lens cloth on both sides. The metal body
    can be cleaned the same way but for a shorter time and if any salts or
    anything else a poshing wheel on a dreamal motor tool to clean out the
    inside and then outside. The lens coatings might be distroyed, but that
    depends on how much gunk is on them.

    Doing this is how I've gotten two of my old german made preset telephoto
    lens for my camera, only thing I had to have done by a repair man was to
    clean and lub the iris & barrle movment areas with the right lub. I've had
    them now for 15 years.
