Why would you wash them? I sell thousands of eggs for eating and all of my customers know I don't wash them and they prefer it that way. It washes away the good flora. The customers wash them as they use them.Just curious but is there a really cheap way to wash lots of eggs? So far I wash them one at a time and use a bottle brush when needed. I typically only wash before using. But it would be nice to save time and wash a dozen or two at once.
