What a rush! I was really pleased to see this post!! The view has always
been,' the queen prefers to lay in dark comb' and through the years I have
seen some disgustingly black stuff. We try to change one third every year.
        Last year we had a speaker from Denmark who is on the Buckfast
breeding program, and they change all frames every year. Mind you they also
have a steam cleaning process where they send all their boxes and frames for
de-waxing and cleaning. The wax is then recycled into foundation.
