    I just opened my Mag-lite flash light and found probably acid that had
    spilled out of one or both batteries. The light was functioning modestly
    several days ago. How do I clean out the debris? Baking soda in a small
    amount of water???

    That will be OK if they are indeed acid batteries. For alkaline use
    vinegar or lemon juice.

    Radio Shack alkaline.

    I'm going to replace them with Energizer Max, alkaline. The others were
    RS alkaline. Still in the package. I can't see the battery time length.
    I had some idea that I would return them, if I couldn't get the debris
    out of the light. However, I'll have to take them out, to check if all
    works. I think I have some in a radio, so maybe all is not lost.

    As Tom said, use vinegar. Put some white vinegar in there and
    scrub with a bottle brush. Repeat several times to be sure you've
    got all the crud out. Then wash the vinegar out with isopropyl
    alcohol.

    I lost a maglite to a leaked alkaline, something swelled up (perhaps
    the maglite case) and I couldn't get the cell out with hand tools and
    a vice.

    It probably needs a drill-press or a lathe,

    ....
    I have x-ray eyes.

    The question remains as to how what mixtures of these remedies are
    required. Baking soda helped. I put in about a teaspoon, and filled the
    handle with water. It did help, but still plenty left. I tried about 2
    teaspoons of lemon juice, and filled the handle with water. Not real
    effective.

    If the batteries have swollen, no amount of baking soda or lemon juice
    is going to get them back to the right size. If they're name-brand
    (the bunny or the copper top), send the whole shootin' match back for
    a replacement. You paid for the insurance when you bought the
    batteries.
