Question

Why the Milk in Milton Thermosteel Flask gets spoiled overnight? Is there any way to keep it fresh ?​

Answer 1

Milk needs a cold temperature to stay fresh. Usually the milk stays fresh for only 6 hours inside a flask. So basically milk is stored at a cold temperature (-4*C). If it is stored in a flask it will surely get spoiled.

Answer 2

Answer:

You actually can put milk in a thermos but it needs to be below 40ºF (4.4ºC) or above 140ºF (60ºC) otherwise harmful bacteria can grow causing your milk to spoil and become dangerous to drink.
