Eli5 why do people say to wash dishes or your hands in warm water when cold slows down bacteria growth?
In: 722
If I had to make an educated guess, it’s because soap is a special type of substance called an “emulsifier,” which means it sticks to both oil and water (which normally won’t attach to each other). This is how it cleans oily dirty goo off you using the running water. And probably that particular chemical reaction happens more easily in the warm than in cold.
Or perhaps it’s just that warm water is more comfortable on the hands.
