Will hydrogen peroxide expire in the fridge?

The short answer is no. Hydrogen peroxide does not expire due to freezing, even in its concentrated form. Hydrogen peroxide is also chemically stable at room temperature, so it will not degrade or break down in storage. However, the high concentration of oxygen-bearing water which can cause injury can degrade the hydrogen peroxide. If you keep your hydrogen peroxide in the fridge, you will reduce the potential risk of harm as the ice will slow down the chemical reaction.

Will hydrogen peroxide spoil?

Hydrogen peroxide has an anaerobic decomposition, which means it will decompose without air. This means that it will not expire or go bad over time. It will still be an effective disinfectant after an extended time. However, if you have to store the solution for more than a few weeks, you should check the expiration date. If you are using a high concentration of hydrogen peroxide, its shelf life will be shorter. A 20% solution can last for up to 50 days
