Hydrogen peroxide typically has a shelf life of about 6 months to 1 year after opening if stored properly in a dark, cool place. Over time, it can degrade into water and oxygen, reducing its effectiveness for tasks like disinfection. It's best to check the expiration date on the bottle and discard any hydrogen peroxide that has passed this date or shows signs of degradation.
