What happens if water in a dishwasher is too hot?

• A. It can bake the foods onto the dishware.
• B. It cleans dishes more quickly with no residue.
• C. It reduces the need for detergent.
• D. It prevents spots on glassware.

Answer: (A)

Too-hot water changes how soils behave during the wash. When the water is hotter than what the cycle is meant to use, food particles and grease can dry out and become baked onto the surface as the dishes heat and dry. This fixes the residue in place, so it’s actually harder to remove in a subsequent cycle rather than easier. So, instead of giving a spotless result, excessively high temperature can leave baked-on stains behind. Detergent amount and the cycle choice still matter for cleaning, and extreme heat isn’t a guaranteed way to prevent residue.
