Keep the lids on the bottle. Tightly screw the lid on so that the milk doesn’t absorb any odours from strong smelling food. If you want to be extra careful store the milk separately from other foods. Never return unused milk back into the original bottle. Once it spends any time at room temperature, milk spoils quickly. When people have unused milk from a jug, especially in restaurants, it is often put back in the bottle which can easily create spoilage. Don’t do this. Avoid exposing the milk to light. Light can destroy many of the vitamins and nutrients in milk such as vitamin D and riboflavin. [3] X Research source Maintain the cleanliness in your fridge.

Always thaw milk in the fridge and if it separates beat it up with an electric blender. For the best results freeze skim milk. Condensed and evaporated milk also freeze well.

Open the bottles or cartons in the order you bought them. Place the oldest bottles towards the front of the fridge and use them first, because if it’s first in, it’s first out.
