Eli5 why do people say to wash dishes or your hands in warm water when cold slows down bacteria growth?
In: 722
In terms of washing greases/fats off dishes, look up ‘micelles’. These are what the surfactant in the washing up liquid creates around the fats in order to solubilise them in water and clean them off. The rate of micelle formation increases as a function of temperature, so hot water is better.
