Re: Extraction question
That is a pretty good policy even though the bleach is unnecessary after use. It is more effective before use.
Supposing it was a group extraction where you are not cleaning between everyone's frames? Like Mark said the risk of infecting your frames is next to nil because the honey is flung out away from each frame as it spins. The honey itself could be very contaminated so as long as you do not feed the honey back to the bees you are alright. You have to eat it all.
