If water without bleach is used for laundry, what temperature should the water be?

• A. 180-200 F
• B. 120-140 F
• C. 60-90 F
• D. 100-110 F

Answer: (B)

Temperature affects how well detergents work to loosen and emulsify soils. When you’re not using bleach for disinfection, using warm water helps detergents do a better job at removing dirt and oils without requiring extreme heat. The 120–140 °F range is hot enough to boost cleaning performance while remaining gentler on fabrics and more energy-efficient than hotter cycles. Water that’s 60–90 °F is often too cool to effectively remove oils, and 180–200 °F is unnecessarily harsh on fabrics and wastes energy. The 100–110 °F range is better than cold but typically not as effective as the 120–140 °F range for many soils.
