How clean do drawn out deep frame combs need to be. I have some that have some mold on them but are otherwise clean. Will the bees clean these up themselves or will the moldy smell cause the bees not tom use them.
I don't want to use bleach to clean them but maybe I could??
Obviously prefer to use drawn combs vs undrawn but presumably there comes a point where the undrawn are preferable.
Any opinions appreciated
