This was given to me by a woman who said her father is/was (?) curator of
antiques in the Victoria and Albert Museum in London.  "With a cheese
grater, grate enough beeswax to fill, loosely, a small jar 2/3 full.  Add
mineral spirits to cover the wax.  Let it stand overnight until dissolved.
Stir.  It should have the consistency of heavy cream.  Apply sparingly, let
it dry and buff vigorously.
