I just wipe if the eggs are particularly dirty.Also, @FortCluck, when we say "wash," do we really just mean "rinse? At the farm, was there any actual soap or scrubbing going on? So glad you had this experience so I can "pick your brain!"
If I have a dirty or poopy egg, I usually just wipe the soil off gently with a wet paper towel. The others get a quick rinse, more like a very quick shower, under warmish water to get any dust off. Does that destroy the bloom, do you think? TIA.
