I have used CN for several years. I first used it on honey supers. Mixed 6 parts
low odor mineral spirits to 1 part CN. I used it as a dip. Took forever for the
"smell" to fade. So, I don't use it for supers anymore. I do use it for outer
covers and bottom boards though. I mix it 3 to 1 for this use. I like to let the
woodenware sit outdoors in the weather for a month or two. Bottoms still have a
slight odor, but it doesn't seem to effect the bees any. If I was going to use it
on supers, I would paint the outsides and top and bottom edges, but not the
inside.
