    Who has a 1.25 gallon container? Sure, you can use a larger
    container, but why not just package it to make 1 gallon of working
    solution?

  2. That is 1 Imperal Gallon. i.e. 1 United Kingdom Gallion.

    That probably works for most countries out side the US that does not use
    metric measurements.

    Have a good day.

  3. I think you have the 1 quart size package. The
    instructions on KHCA can be confusing because they show
    mixing both stock and working solutions. Unless you have
    need for all of it at once mix it as a stock solution. The 1
    quart size makes one quart of _stock_ solution. This is
    diluted 1 part stock to 4 parts water for the _working_
    solution, that is, one quart of stock makes 1.25 gallons of
    working solution.
    The life of the working solution is short, it should be
    mixed shortly before use and discarded. Stock solution will
    last about 2 months in a filled, closed bottle (Kodak
    numbers). Since the solution does not turn color or give any
    other sign of having oxidized one must keep track of its
    age. When exposed to the air the Sodium sulfite, the main
    ingredient in KHCA, turns to Sodium sulFATE. The sulfate
    does no harm but is not nearly as good as sulfite as a wash
    aid.
