Unfortunately, the average shelf life of liquid bleach (being stored between 50 and 70 degrees Fahrenheit) is around 6 months. After that, bleach will lose 20% of it’s strength at around the year mark and then 20% each year after that. So if you’re not vigilant about keeping it rotated, chances are when you need it for disinfecting water or to keep things clean you’ll be fresh out of bleach and luck.
