What is the minimum temperature for rinse water?

• A. 180F
• B. 140F
• C. 120F
• D. 212F

Answer: (A)

Rinse water must be hot enough to sanitize what’s been washed. For hot-water sanitizing dishwashers, the final rinse needs to reach at least 180°F (82°C) to reliably kill or inactivate pathogens on dishes and utensils. Temperatures like 140°F or 120°F are not sufficient to achieve sanitization, and while 212°F is boiling, it isn’t necessary or practical in typical dishwashing operations. Maintaining 180°F ensures effective sanitation while keeping equipment operation feasible and safe for workers.
