The present invention relates to methods of sanitizing the shells of eggs, which are used for human consumption and also as hatchlings. More specifically, the present invention relates to a method of sanitizing eggs using an electrostatic sprayer with electrolyzed oxidizing water produced from an electrolyte solution. It is the overall objective of the present invention to provide a method for sanitizing eggs comprising the steps of passing an electrolyte solution through a water electrolysis machine in combination with feed water to produce electrolyzed oxidizing water, and then spraying the eggs with the electrolyzed oxidizing water by using an electrostatic sprayer which creates a negative charge on the spray droplets as they leave the sprayer.
