What is the recommended wash temperature in manual warewashing?

• A. 120°F
• B. 110°F
• C. 171°F
• D. 180°F

Answer: (B)

In manual warewashing, the wash water should be warm enough to help the detergent cut through soils but not so hot that it risks burns or damages. The recommended wash temperature is 110°F because this level provides effective cleaning action without compromising safety for staff or delicate dishes. Higher temperatures, like 171°F or 180°F, are associated with sanitizing steps in high-temperature dishwashers rather than the washing step in manual cleaning. So 110°F best fits the purpose of cleaning in a manual process, while sanitizing requirements are addressed separately through hotter final rinses or chemical sanitizers.
