What is the appropriate water temperature for the first tub used in setting up sinks?

The appropriate water temperature for the first tub used in setting up sinks is hot, soapy water. This choice is correct because hot water is effective for sanitizing surfaces and dissolving grease, which is crucial in a bartending or food-preparation environment. The addition of soap aids in breaking down contaminants, ensuring that tools and surfaces are properly cleaned and safe for use.

Using hot, soapy water helps to eliminate bacteria and other harmful pathogens that could be present on surfaces or equipment. This is particularly important in settings where food and beverages are prepared, as maintaining hygiene is essential in preventing cross-contamination and ensuring customer safety.

Other temperature options, such as cold or room temperature water, would not be as effective in eliminating substances like oils and bacteria. Warm water might assist to some extent, but it does not provide the same level of sanitation as hot water can when paired with soap. Therefore, starting with hot, soapy water ensures a higher standard of cleanliness right from the beginning in the setup process.
