What must be done if a walk-in chiller is not clean?

If a walk-in chiller is not clean, it should be thoroughly cleaned and sanitized to prevent food contamination and ensure proper functionality. This involves removing all food items, wiping down surfaces with appropriate cleaning agents, and addressing any spills or mold. Additionally, it's important to check and clean the condenser and evaporator coils to maintain efficient operation. Regular maintenance schedules should also be established to prevent future buildup.
