I truly believe God knew what He was doing. There is a natural coating around an egg called the bloom. It protects the insides of the egg so that stuff does not get inside the porous shell. And when you wash the egg you take off this layer of protection and its freshness. Egg shells are porous so once the bloom is removed it soaks up what is around it and deteriorates faster.
Commercial eggs are bathed in a chlorine solution. Yes, that chlorine impacts the actual egg itself. I do a dry clean or vinegar to wash eggs. A lot less toxic than what you are getting from the store.
Hope this helps,
* I do wash eggs for personal use right before use.
