Just some thoughts I've got.
If there's a lot of dust on the frames and wax, the bees are likely not going to mess with it. That's at least as I understand it I have not experienced this.
Not sure where your frames have been sitting for the past, but I keep mine in the deep-freeze overwinter. After doing my last harvest I leave it on for another week so they can remove whatever honey residue is left on their and they will likely move that to open cells in the brew chambers. The freezing, helps kill any organism that may be on the frames at least as I've read or understood.
I pulled mine out of the deep-freeze let them set their for approximately a week and then I put them on the hive, literally within one week it was about 65 to 75% full of un-capped honey. I was shocked on how quickly the girls went to work.
