You can test the old comb theory, when you taste the the winter sugar aroma after 6 months in old combs and in new combs.
What ever, I do not have afford to cast away "used combs". Each productive hive has 60 frames. To draw combs has taken 40 kg honey. The most idiotic thing is Bailey comb change.
To keep apart brood combs and honey combs. There is no reason to that.
If you are afraid of larva poo, it just belongs to honey system like legs of milk cow. Legs are dirty.
Aroma of honey is what it is. Not much ways to affect it. I take all what I get.
I abandon the comb when sun light does not come through.
My queens lay into honey combs too. The more they lay, the better.
