What is the minimum water temperature recommended for handwashing?

• A. 100 degrees Fahrenheit
• B. 90 degrees Fahrenheit
• C. 110 degrees Fahrenheit
• D. 120 degrees Fahrenheit

Answer: (A)

Warm water is used for handwashing because it helps soap lather and rinse effectively while staying comfortable on the skin. The minimum warm temperature commonly cited is about 100°F, which balances effectiveness with safety—hotter water isn’t needed and can risk burns, while cooler water may be less comfortable and reduce thorough washing. The key to clean hands is proper technique: wet, soap, scrub all surfaces for about 20 seconds, rinse, and dry.
