4. Household Cleaning
a. Polish Silverware
Sour milk can help remove tarnish from your silver items. Soak them in sour milk for a few hours, then rinse and buff them to a shiny finish.
b. Clean Grease and Grime
The acidity in sour milk can cut through grease. Use it to clean greasy pans or as a pre-treatment for greasy stains on clothes.
5. For Pets and Livestock
a. Feed for Farm Animals
Farm animals like pigs and chickens can safely consume sour milk as part of their diet, providing them with additional nutrients.
b. Pet Treats
Mix a small amount of sour milk into your dog’s or cat’s food as a treat, but ensure it’s still safe and hasn’t gone too far beyond its expiration date.
When to Toss It?
If the milk has a rancid smell, curdles excessively, or shows signs of mold, it’s time to discard it. But in most cases, slightly sour milk can be a goldmine of utility.
Before you toss out that expired milk, consider these eco-friendly, creative uses. From cooking to gardening, sour milk can serve a second life, saving you money and reducing waste!
