How do you clean your eggs?

[cindy57]

I'm getting an egg about every other day. Bought my chickens last spring. I rinse off the eggs in cool water. sometimes i use a wet paper towel to scrub them. Most of the eggs are a greenish color but even after rinsing they still look kind of dirty.is there something i can use i know the eggs are pourus and we eat them so i don't want them to get contaminated.
thanks
cindy
