Stewarding SOP for The Basics of Warewashing

In a busy kitchen, the dishwasher is often the unsung hero. However, without proper training and attention to detail, the kitchen’s entire operation can suffer. That’s why it is crucial for all kitchen stewards to understand the basics of ware washing.

First and foremost, it’s important to understand the three-compartment sink method. This involves using three separate sinks for washing, rinsing, and sanitizing. The washing sink should contain hot, soapy water, while the sanitizing sink should contain a solution of water and sanitiser. Additionally, it’s important to frequently change out the water in each sink, especially as it becomes dirty or contaminated.

Another key aspect of proper ware washing is understanding the importance of temperature. Water that is too hot can damage dishes, while water that is too cold may not effectively clean and sanitize them. It’s essential to follow manufacturer guidelines and recommended temperatures for both the washing machine and the three-compartment sink.

Lastly, kitchen stewards should be aware of the different types of dishwashing detergents and sanitizers available. Each kitchen may have unique needs depending on the types of dishes being used and the water quality in the area. By selecting the right products and following proper procedures, kitchen stewards can ensure that dishes are not only clean, but also safe for customers to use.

Overall, mastering the basics of warewashing is crucial for any kitchen steward. By following proper procedures and paying attention to detail, they can help keep the kitchen running smoothly and ensure that customers receive clean, safe dishes every time.

Establish standard policies for the proper procedure for washing and sanitizing kitchen equipment, kitchen utensils, and F&B service equipment to reduce microbiological contamination and chemical contamination to prevent proper cleaning concentration and contact time in the process.

The Executive Chef and Stewarding Manager should be responsible for ensuring that appropriate kitchen equipment cleaning and maintenance methods are followed by the stewarding staff. The hotel training and HRD department should develop and implement proper written Kitchen Stewarding SOP’s to ensure the same is implemented correctly throughout all the food preparation outlets.
