What is the wash solution temperature for stationary rack, dual-temperature machine, and multi-tank, conveyor, multi-temperature machine?

• A. 180 degrees F
• B. 150 degrees F
• C. 160 degrees F
• D. 170 degrees F

Answer: (B)

The wash solution temperature is set to 150°F to balance cleaning power with safety for ware and equipment. At this temperature, detergents work effectively to lift soils and fats, while avoiding damage to dishes and plastics that can occur with hotter water. In these machine types, the wash step and the sanitizing rinse are separate: the rinse is typically hotter (around 180°F) to sanitize. The other temperatures listed are higher than what's needed for the wash step and are more relevant to the sanitizing rinse. So, 150°F is the optimal wash temperature for stationary rack, dual-temperature, and multi-tank conveyor, multi-temperature machines.
