    Rinse it down with a quality, non-residual, component cleaner followed by careful application of conformal lacquer...

    Edit: Re: your poll --- Please don't even think of applying electrolytes to electronic assemblies!:eek:

    Note, also, that while isopropanol may be an effective cleaner/solvent it is incompatible with some polymers (e.g. polystyrene)

    I have had good experience with the products linked below :)

    Note: Owing to its acrylic base, the lacquer linked below will not complicate future repairs...

    FWIW Chemtronics, Allied and 'GC' branded chemicals are often available from 'bricks and mortar' NTE distributors...

    The poor man's version is to
    1) rinse with a lot of warm/hot water, perhaps with a drop of surfactant (dishwashing detergent),
    2) shake and blow away most of the water,
    3) immerse in isopropyl alcohol (90% or more) to pull out residual water
    4) Shake and blow again and allow to dry

    This process works pretty well for dirty keyboards and such.

    Vinegar might be OK for brief treatment, if no power is present. It's a weak organic acid and won't dissolve much metal. More importantly, it's volatile and won't leave residue. Baking SODA (don't think about POWDER, it's different) won't do much damage but is difficult to remove. It won't evaporate.

    I'm afraid a one-post member can't display a link to a business. :(
    and if he does, I'm afraid the Moderators will delete it. :eek:
