How do I clean the stains on blue eggs before I incubate or even pass them on to other folks to eat? Even after washing blue eggs, it sometimes looks like they have stains on them, but they are clean. It is a turn off for some people... I use dishwashing liquid with a teflon scouring pad, very gentle...I don't want to use anything like bleach or a strong chemical. The blue eggs really stain badly, especially if the girls are free ranging and we have had rain and they lay some eggs in the mud... Yipes. By the time I get to them in the early evening, the stains have set in and when I wash them, it looks as though I never did wash them Help!!!
