What is the most commonly used chemical in the dish-room?

In a dish-room, ensuring cleanliness and safe food handling is crucial. The most commonly used chemical is detergent. Detergents are specifically formulated to break down and remove food residues, grease, and grime from dishes, utensils, and equipment. They help to prepare surfaces for sanitizing by effectively lifting and emulsifying soil, making subsequent cleaning steps more effective.

While other products like sanitizers are vital for killing pathogens after cleaning, they are typically used after the detergent step. Chlorine bleach, while useful for disinfecting, is not the primary product for initial washing and could potentially damage some materials if used improperly. Vinegar can be used as a natural alternative for cleaning but is not as effective as detergent for the heavy-duty cleaning often required in a busy dish-room setting. Thus, detergent is the most common choice for daily use in the initial cleaning process of dishware.
