> Dear Bill:
 
In all my readings I have not found one that indicates that mineral oil
deteriorates, oxidizes, etc.  Nor have I found that it causes any
undesirable effects on wood.  On the contrary, it seems to preserve the
wood.  I used to see mold in some of my hives during the winter months
but I haven't seen mold this year.  I would be interested in reading
literature to that effect should there be any and someone could refer it
to me.Best regards.
