Final answer:
It is true that under certain circumstances, such as lack of a dishwasher or dealing with delicate items, it is acceptable to wash dishes in the prep sinks. It is imperative to follow proper sanitation procedures and ensure the prevention of cross-contamination when doing so.
Step-by-step explanation:
Under some circumstances, it is true that it is acceptable to wash dishes in the prep sinks. However, in a professional kitchen, prep sinks are typically designated for preparing food and separate from dishwashing areas to prevent cross-contamination. When a dishwasher is not available, items that may be damaged by dishwashing machines and strong detergents, such as those made of silver, fine glassware, and certain metals, should be hand-washed using dishwashing liquid and possibly in a prep sink if it does not interfere with food preparation and if proper sanitation procedures are followed.
The concept of cleanliness is indeed relative and depends on the intended use of the items being cleaned. While dishes in a household setting might not require the level of cleanliness needed for surgical instruments, they still need to be free of soap residue and leftover food particles to be considered safe for use.
