Do you keep a carton of milk in the rack on the inside of the refrigerator door? That's not the best place.
What is the best place for milk?
On the inside of the door, the carton of milk is exposed to warmer air every time you open the door. It is best to put the milk in the back of the refrigerator, where the temperature is usually the lowest.
Expiration date In general, milk is still safe to drink until about 2 to 3 days after the best-before date. It is wise to sniff it first.
