Hydrogen peroxide

[Queso]

Hydrogen peroxide.

Does it go bad?

 

I only say this because I've been thru about half a bottle in 2 weeks and it's started smelling differently.

Is this due to the volume of the solution compared to the volume of the container?

Or is my disinfectant infected?

Or.... :winter_brr:

 

It honestly smells like smelly feet. Like valarian root.

I don't have the slightest idea what could be causing that smell.

Hydrogen peroxide doesn't go "bad", it just decomposes really easily: into Water and Oxygen.... neither of which smells.

 

Is there any chance something accidentally got in there? Any other chemical?

Maybe when your opening it and closing it over the two weeks, air gets at it and causes some sort of reaction...like Jam.

[Queso]

wiki says that "hydrogen peroxide has been replaced recently by better smelling solutions"

or something like that.

 

Does your hydrogen peroxide smell?

Hydrogen peroxide is odorless...

and I have a bottle that's been half-empty for a couple months now. No odd smell there.

[Queso]

Has anyone ever experieneced this?

I can relate Orb.

I've often caught a distinct odor from a H2O2 bottle. I can offer no explanation though.

 

I just tested my bottle that I've had for about 2 months now. It was opened the first day and never opened since. I left it in a cool dark area.

It had zero smell.

 

So now I'm wondering if the smell I have gotten was from something else, but the funny thing is that the smell has always been the same.

 

MB is right though, it's not *supposed* to smell.
