    Forgive me if I am wrong but doesnt that sound along the lines of a heated
    (concentrated) Coke or Pepsi solution? <grin>

    There are some words on pickle alternatives in the 'Shop tools' article on
    the tips page. Vinegar and salt are reasonable one, alum which is used for
    making pickles and found in the supermarket makes a good pickle, almost no
    fumes apparently, about one ounce per three liters of water or so is
    supposed to work well. Ever wondered why we call it pickle? It is because
    jewelelrs used to use alum for pickling with.
