Maybe butric anhydride (Bee Go or Honey Robber) won't get into honey, but the
stink will get into the cappings.   I once made a Fair wax block from
cappings taken off with Honey Robber, and when the block was unwrapped at the
Fair it stunk of butric Anhydride (and the block was appropriately penalized
by the judge).   I now use benzaldehyde, and have had no problems with
strange smells in my wax or honey.
