Baking soda is a very mild alkaline powder, which will be slightly corrosive when dissolved in water, and it is easier to remove dirt than clean water. In addition, baking soda powder will produce carbon dioxide when it meets water, which can produce stirring function, so baking soda can play a role in slightly soiled areas or objects, especially those who are allergic to detergents. You can add a little baking soda to dishwashing water, so as not to burn your hands, but also to wash bowls and plates very clean.
