Yes, you can safely wash them. Use warm water to get the stuff off--the theory is that using water warmer than the egg will not force bacteria into the egg--It's a thermal properties thing. Then rinse them in a weak bleach solution--1TBL bleach per gallon of water, contact time one minute. This will not remove the bloom and I have cleaned dirty eggs--they hatched fine for me.
