We extracted several weeks ago. After letting the bees clean the frames, we sprayed the frames with BT for wax moths. I stacked the supers up in the garage. Well I didn't think about the ventilation. Now they have mold starting to grow on the frames and on the comb. I just made a large screened bottom frame to set the supers on and get them off the ground for ventilation. What can I do to stop the mold? Would it be ok spray the frames with water and bleach and let dry before winter storage?
