20 Brilliant Ways to Repurpose Old, Spoiled Milk

19. Helpful Tip: Freezing milk makes it last longer

Have you noticed that circular indent on the sides of milk gallons? If they bulge outward, then your milk is rotten and needs to be used as a polish, soup-thickener, meat marinade, or skin moisturizer ASAP. However, frozen milk will also cause the circle to pop out, which is a good thing if you purchase milk in bulk. Keep your milk in a chiller and defrost it in a refrigerator. This will extend the life of the milk by over a month. Alternatively, you can purchase milk in powder form if you aren’t big on drinking gallons of milk.
