    I have accidentally dropped the end of a shore power cord into salt water a
    couple of times. At my marina, they have ground fault protection at the dock
    box, so any internal conductivity instantly trips the shore power breaker on the
    dock. I found that the following process works well to get rid of the salt
    and dry the connector. First, it the connector can be disassembled, do that. In
    any case, immerse the parts in fresh water that has some Salt Away mixed in.
    Then rinse in fresh water and dry in the sun or, better yet, place the nozzle
    of a vacuum cleaner against the openings, wrap with some tape, turn on the
    vacuum cleaner and go have lunch. The lowered pressure from the vacuum causes fast
    evaporation of the water.

    I have successfully used this vacuum process to dry our electronics, even a
    lap top that got rained on. Put the item in a plastic bag, vacuum nozzle
    inside, and give it some time.

    When I worked in high tech we had electron microscopes. Before putting the
    object into the microscope, it first went into a small sputtering machine for
    gold plating. Before the sputtering process you had to pull a pretty high vacuum
    with a special pump ( fomblin oil pump). Back in those days, watches often
    got water inside and it would fog up the crystal from the inside so the watch
    couldn't be read. A few seconds in the vacuum chamber removed any trace of
    moisture. Same principal but much slower with a vacuum cleaner.

    De Fever 41, done the loop, on our second go round. Boating 50 years, mostly
    sail.
