It turns out that almost everyone has been putting their milk in the fridge wrong all their lives.
Go to a house anywhere in Ireland and you will find all the milk perched in the door section of the fridge pretty much everytime.
The dairy product is one of the most used items in a fridge so it makes sense to put it there for convenience.
But it turns out that putting dairy products, especially milk, in the door of the fridge is a bad idea.
Why you shouldn't keep your milk in the fridge door
It turns out according to housekeeping experts that your fridge door is in fact the warmest part of it.

Makes sense right? It's furthest away from the actual coolers and everytime the fridge opens it is brought out of the cool zone.
This is particularly important for dairy products given how easily they can go sour when subject to room temperature.

Where I should I keep my milk?
Goodhousekeeping.com, a site based solely on keeping your house well, suggest that you should keep your dairy products in the lower or middle shelves.
Why? Well because they are the coldest parts of your fridge and will keep your milk for the longest.
