I have been using this egg washing detergent for 3 years now. I have 45 laying hens and a good customer base for my egg gate sales. A teaspoon of this egg washing detergent in a sink of warm/hot water and a regular scrubby cleans my 40 something eggs everyday. A good rinse and the eggs dry to a nice looking clean and safe egg to sell my customers. If you wash your eggs, I highly recommend it.
