Eli5 why do people say to wash dishes or your hands in warm water when cold slows down bacteria growth?
In: 722
Warm helps break up food-stuffs and oils on dishes.
Cold slows bacteria growth. (still grows, just slower than normal)
Hot KILLS bacteria. (lowers the amount of bacteria – possibly to nothing, depending on temp and exposure time).
The dish-soap’s despite main function, despite the bacteria-killing claim, is a degreaser. It cuts through oils and helps loosen the bio stuff on the dishes – works better as the temp increases.
