What can expired milk do

Expired milk can be used for cleaning, skincare, gardening, and other purposes, but cannot be consumed. After milk expires, protein and fat denaturation may produce harmful substances, and direct consumption may cause gastrointestinal discomfort. The lactate content in expired milk increases, making it suitable for use as a natural cleaner. Mixing expired milk with water and wiping leather or wooden furniture can have a polishing effect. The fat content in milk can nourish the surface of leather and wood, and even minor scratches can be repaired. For silver that has oxidized and turned black, soaking it in expired milk and then wiping it with a soft cloth can restore some of its luster. Areas with heavy oil stains in the kitchen, such as range hood filters, can soften stubborn oil stains by soaking them in warm expired milk. The acidic nature of spoiled milk has certain benefits for the skin, but it should be used with caution for sensitive skin. Lactic acid can gently exfoliate. Mix expired milk with oatmeal powder to make exfoliating facial mask. Milk bath can help soothe the skin after sun exposure, but it is important to ensure that the milk only slightly spoils and does not mold. Expired yogurt like milk can be applied to the hands to soften keratin, and rinsing after ten minutes can make the skin softer. In terms of horticulture, diluted expired milk can be used as a natural fertilizer to provide calcium and protein nutrition for plants.

When using expired milk, pay attention to whether it has become moldy or emits an odor. Moldy milk may contain harmful bacteria. It is recommended to conduct a small-scale test before cleaning or skincare to avoid allergies or irritation. Although expired milk has various uses, gloves should still be worn when handling to avoid direct contact with spoiled liquids. If you accidentally drink expired milk and experience symptoms such as abdominal pain and diarrhea, seek medical attention promptly.
