Yes, I know all that, and I used to leave the bloom on. But, I'm a germaphobe, so I couldn't deal with it. Messy eggs get washed in warm soapy water, literally a couple drops of soap. I used to buy the egg wash soap, then got to thinking they use Dawn on birds caught in oil slicks. It works better and is safe. My eggs never last more than 4 weeks and they are always refrigerated. I supply a couple neighbors and myself with only 9 chickens. They don't taste like soap and I have yet to have a bad egg in 4 years.
