Conuctivity of spray lube?

    Sorry to clutter the forum with a real basic question, but I have an
    electronic display piece that needs maintenance. There are plastic
    gears that make the piece rotate; the rotation feature is running very
    rough and there is exposed wiring near the gears. If I spray some wd40
    in there to see if the gears are running rough due to dryness, etc,
    will that affect the wiring? Does spray lube conduct current?
     
  2. I doubt that conductivity will be a problem with any lubricant that is
    not specifically designed ot be conductive. But WD40 is a poor lube
    for plastic gears. I think white lithium grease would stay on the
    teeth and last lots longer.

    Thanks, but can that be sprayed? I can't reach into the mechanism, and
    I don't want to risk taking it apart...yet.

  7. Get a straw or a coffee stirrer, put a bit of grease on it, and dab it on
    a gear. A little goes a long way.

    Or is the mechanism sealed somehow? Is appearance important? Spraying
    would probably smear any plexiglass casing.

    I think they make spray lithium grease still. I have a can of it, somewhere.

    DO NOT UNDER ANY CIRCUMSTANCES USE WD-40 !!!!!!!!!!!!!!!!

    I did this once, and it took me WEEKS to clean the crud out of the
    mechanism.

    Get some proper contact cleaner, or EXTREMELY light-weight penetrating
    oil, or, for that matter, soapy water.

    But WD-40, after it makes your hinge stop squeaking, turns to 180 weight
    vaseline.

    Good Luck!

    He has to get the dirt out somehow before he can ever expect the mech to
    run smoothly again.

    Contact cleaner, and if possible, some kind of spray solvent that doesn't
    attack plastic, but don't add any more crud before you get the crud that's
    causing the problem fixed first!

    Good Luck!

    first use a light solvent to clean the dirt out, beware of the solvent not
    to attack plastics
    then you might rince it using hot soapy water
    have it dried thoroughly
    next use some lubricant (machine oil,...)

    only using cleaners just displaces the dirt, by which the dirt will cause
    probs later on

    Are you guys forgetting that he doesn't want to take it apart? Cleaning the
    crud out is only effective if he can get the dirt *out* of the mechanism. I
    would use machine oil on plastic gears. Machine oil is used for spindles,
    motors, etc where there's no plastic parts. Lithium grease (white) is best
    for plastics.

    Cheers,

    Correction: wouldn't use machine oil on gears.

    Many of those parts *do* have smaller or larger holes in them
    that's how the dirt gets in in the first place.....

    Thanks for all the useful info, and after reading all the replies, I
    have decided to return the item (it was an ebay purchase). I will try
    again with another auction that lists the item as mint and/or perfect
    working condition.
