    My my my! 

    Actually, I did answer this before-- more than once over the years,
    and once recently. 

    There is no fixed proportion. Dump some boric acid in a lidded
    container-- say, a couple of tablespoons per cup of volume-- and
    fill it up with alcohol. Stir it or swirl it every time you use it,
    dip the workpiece down to the bottom and swish it around. Most of
    the boric acid won't dissolve, and will settle back to the bottom,
    but that's OK. 

    Keep adding alcohol as it evaporates off. When the layer of boric on
    the bottom gets a bit thin, add some more. 

    That's it! 

Noel
