What action should be performed at the end of a shift regarding the steaming wand?

At the end of a shift, flushing the steaming wand is crucial for maintaining equipment hygiene and functionality. Flushing involves running a small amount of steam through the wand to clear any milk residue or buildup that may have accumulated during use. This process prevents clogs and ensures the wand remains clean, which is important for both health standards and the quality of future beverages.

While wiping down the wand is helpful for surface cleaning, it does not address any internal residue or blockage that may affect performance. Purging refers to releasing steam or hot water to clear out any obstructions, which is part of the flushing process but is more related to immediate preparation before use. Calibrating the wand would not be necessary at the end of a shift, as this is typically performed only when equipment is not functioning correctly or requires adjustments. Thus, flushing the steaming wand ensures it is ready for the next use, promoting proper maintenance and hygiene in the coffee preparation process.
