Final answer:
Detergent is not a type of approved cleaner used in foodservice operations.
Step-by-step explanation:
The answer to the question is detergent. Chlorine, degreaser, and delimer are all types of approved cleaners used in foodservice operations. Detergent, on the other hand, is not a type of approved cleaner used in foodservice operations. Detergents are typically used for cleaning dishes and utensils in dishwashers, but they are not suitable for direct use on food preparation surfaces. Foodservice operations typically use approved cleaners that are specifically designed to be effective against foodborne pathogens and safe for use in food handling areas.
