Question

How long does hydrogen peroxide last on the shelve. If there is no expiration date on the bottle?

Answer 1

thats a hard question if you do not multiply alot

depend on how much is in the bottle if its like 50ml then 68hour and 21minute ,32-54 sec

Answer 2

If it's in doubt I'd say just throw it out and buy a new bottle.  If you have a cut you need to clean you could just try it and if it bubbles it still works if it doesn't it's mostly water and you're fine.

Answer 3

I imagine that it doesn't last very long. Don't know any numbers, sorry.
