The shelf life of sodium hypochlorite 12.5%, such as the product offered per gallon from our NJ warehouse, is generally 3 to 6 months if stored in a cool, dark location. Exposure to heat, light, or air will accelerate degradation. To maintain the potency of 12.5 sodium hypochlorite, regularly check concentration and always store it tightly sealed. Proper storage is essential if you buy sodium hypochlorite for disinfection or bleaching purposes.
