What is the purpose of filling the second sink with clean water?

Filling the second sink with clean water serves the primary purpose of rinsing off food particles from dishes and utensils that have been cleaned in the first sink. The two-sink method is a standard practice in food safety and sanitation, where one sink is designated for washing with soapy water, while the second sink is used for rinsing. This ensures that all food residues are adequately removed, minimizing the risk of contamination and ensuring that the items are safe for use.

In a commercial kitchen environment like Starbucks, proper cleaning protocols are essential to maintain hygiene and prevent foodborne illnesses. The use of a separate sink for rinsing allows for thorough cleansing, as it provides a clear area to eliminate any remaining debris after washing.
