I don't wash mine but will wipe icky stuff off of them. Mom used to just go collect, crack, and cook them when I was younger. Guess I picked that up from her.
I am interested to know if we should wash them. I try not to "overdo" around here on the cleaning to a sterile environment as I feel we all need a few germs to keep our natural immune system going. Not that I keep a dirty house or never wash my hands!
But I just don't really feel the "need" to wash the outside of the egg if I am not going to eat the shell. And I always have to wash my hands after cracking an egg b/c I have YET to manage to crack an egg w/o getting some of the white on me!
Eating eggs I use soap to wash them off, but only if they are dirty.
I don't even use soap...lol. I just dampen a napkin or paper towel with water (the ones I keep/use myself). Even the ones I wash off better for family, I just use plain water, but I actually hold them under the tap.
