Which chemical is specifically not food contact surface safe and requires rinsing?

Greaselift is specifically not food contact surface safe and requires rinsing because it contains potent cleaning agents that can leave residues harmful if ingested. These residues may not make the surface safe for direct contact with food items, which is a critical aspect of food safety in any establishment, particularly in a restaurant environment like Cactus Club. Rinsing is a necessary step after using Greaselift to ensure that any chemical remnants are completely removed from the surfaces where food is prepared or served. This ensures that the cleaning agents do not contaminate food, maintaining the health and safety standards required in food service operations. In contrast, the other chemicals listed are formulated to be safe for food contact surfaces, which allows them to be used without requiring the same level of caution regarding rinsing.
