WebJan 10, 2024 · What is the shelf life of 35% Hydrogen peroxide? It depends how we define shelf life. Hydrogen peroxide does not spoil or “go bad”. Our 35% Hydrogen Peroxide does not have unwanted added stabilizers and is not “stabilized” with added chemicals or toxic heavy metals. For this reason on average a 1%-1.5% loss over 12 months may be …
