    [1] Remove all power sources. Unplug the device and
    remove all batteries, including soldered in batteries
    if you can.


    [2] Disassemble the device as well as your skills allow.
    If there is a paper cone speaker or other part that
    looks like it might be damaged by water, set it aside.


    [3] Go outside with a garden hose or put it in the sink
    and flush it with clean water to try to remove any
    soap, coffee, urine, or whatever else you managed to
    get in there.


    [4] Use a 1/2 gallon jug of distilled water (make sure it's
    the distilled kind) and flush out the normal water.


    [5] Use a bottle or two of isopropyl (rubbing) alcohol to
    flush the distilled water out. For antique devices
    that may have natural rubber in them, use pure drinking
    alcohol. In either case, the higher the proof/percentage
    the better.


    [6] Put it in a warm, dry place until you can't smell any
    alcohol. Then leave it for at least another day before
    reassembling and testing.


    [7] If you are in a hurry, you can try to accelerate step
    six with a fan, blow drier, etc. It's up to you to
    insure that you don't start an alcohol fire.

    Hi Guy,

    IMHO,
    Step #1 should be: "DO NOT attempt (FIGHT THE TEMPTATION) to power it up it
    see if it still works!"


    We used to sell cellular phones, and we'd get a "liquid damage customer"at
    least once per month.

    First question: "Have you tried powering it on?"
    If the answer was "Yes", our responce was "Well, it's probably TOAST, then!"
    The look on their face when the realization hit them was a little sad, but a
    little bit funny, too.

    [6a] If you use pure drinking alcohol, fight the urge to let it
    drain into you mouth.

    (6b) Reduce drying time by licking off any excess alcohol.

    What about for electronics that are still working but are full of water
    especially things like static inverters , fluro light balasts , transmitters
    , industrial pcs etc ?

    The water will cause ionic corrosion, thus converting the working
    unit into a nonworking unit. This can happen in a week if you
    spilled, say, salt water in it, or it could take months if the
    liquid was tap water. If you are lucky the failure will be an
    open circuit and the unit will go dead. If you are unlucky it
    will be a short circuit and the unit will catch on fire.

    Simply letting it dry does not remove the deposits that promote
    corrosion. GMCFESIL: (Guy Macon's Cure For Electronics Soaked
    In Liquids) does. Once dry, the damage comes from humidity and
    the minerals/salts deposited on the circuitry, which means that
    the unit may survive for years in a dry desert environment, but
    go bad in a few weeks in a humid environment.

    If the liquid has an organic component (coffee with cream, soda,
    blood, urine, etc.) it can promote insect infestations, bacterial
    growth, or mold.

    (Feel free to insert humorous comment of your choice here
    concerning how one manages to soak a PC in blood or urine.
    extra points if you mention Bill Gates.) :)

  10. Someone misunderstood the concept of "p-code"?
