I have a 50 cigar humidor in which I am using the Humi-Care blue stick. The box has 40 or so sticks in it and the temp is 75 constant and 72% humidity constant. For some reason I have a white residue on my sticks, it wipes of rather easy, my concern is what in the heck is it. I was careful to season the box and make sure it was dry before loading it. Cigars were in it for 4 months with no issue, then the white crap appeared. Anyone run up against this? Do I need to trash the sticks and clean the box, I am pretty much at a loss at this point.
