To effectively remove grease from dishes, they should be washed in:

Using hotter water to wash dishes is the most effective method for removing grease. Heat helps to dissolve fats and oils, breaking them down so they can be more easily rinsed away. When water temperature increases, the molecules move faster, which enhances the cleaning power of detergents and enables better emulsification of grease and dirt.

Colder water, room temperature water, or chilled water do not provide the same cleaning efficacy because they do not aid in melting or dissolving the greasy substances as effectively as hot water does. This is especially important in tasks such as washing greasy pots or pans where food residues contain fats that require higher temperatures to effectively separate and remove them from surfaces. Hotter water thus optimizes the cleaning action and ensures that dishes are thoroughly cleaned.
