The shelf life of 12.5% sodium hypochlorite, commonly used as a disinfectant or bleach, is typically around 3 to 6 months when stored in optimal conditions—cool, dark, and tightly sealed to minimize degradation. Over time, exposure to light, heat, and air can cause the solution to degrade, reducing its concentration and effectiveness. It's important to regularly check the concentration if it's used for critical applications.
