If wash water is excessively hot, which statement is true?

• A. The foods will not bake onto the dishware.
• B. The foods may bake onto the dishware.
• C. The cycle will always run faster.
• D. Detergent will always be ineffective.

Answer: (B)

Excessively hot wash water can cause soils to bake onto dishware. When the water is too hot, moisture on the surface evaporates quickly and any food residues can brown, set, or caramelize, forming a stubborn film that detergent has trouble removing. So even with washing, foods may bake onto the dishes. The cycle speed isn’t guaranteed to be faster just because the water is hotter, and detergents aren’t necessarily rendered completely ineffective, though their performance depends on staying within the detergent’s designed temperature range.
