What cleaning process requires the glass to be treated heel in, heel out?

The process of rinsing in cold water requires the glass to be treated heel in and heel out in order to effectively remove any residual soap or cleaning agents from the surface. This technique ensures that the entire interior and exterior of the glass are thoroughly rinsed, preventing any remaining cleaning chemicals from affecting the quality or taste of the beverage that will be served in the glass.

This method is essential for maintaining glass hygiene and ensuring that the glass is properly prepared for use. A heel-in, heel-out technique allows water to flow freely through the glass, ensuring comprehensive rinsing. Other processes, such as washing or sanitizing, may use different methods, and drying generally involves positioning the glass upright or inverted, not the heel-in, heel-out strategy.
