How long is 3% hydrogen peroxide good for?
- 0Sep 16, '07 by KROkay. I am drawing a blank on this one. Had a friend ask me how long 3% hydrogen peroxide is good for once the bottle is opening. I know it lasts a lot longer if you keep it in the dark bottle it comes in. However, I do not know how long it lasts. The friend is a non-medical person that is curious. Anyone have any idea? Thanks in advance

hydrogen peroxide ...
...the average shelf life of a bottle is about a year but once you open it and use it, the potency decreases slightly. that’s not to say that it will be any less effective in cleaning out wounds or for gargling – but it does lose its potency over time so its important to check the expiration date and if possible replace a bottle sixty days after its been open so you’ll get the best results. ..
