Of all the things we buy for SHTF Hydrogen Peroxide, while an excellent tool, suffers from an absolute “Use by Date” deficiency.

When you buy H2O2 keep in mind it will absolutely expire and its efficacy will deteriorate exactly 3 years from when you buy it.

I mark the bottles in permanent ink of when I bought it and write in big “type” its expiration three years from that date.

Can’t tell you what to do with it when it expires but, I have tested 3 year +1 day H2O2 and it’s absolutely a dud.

So I also write the date 2.5 years from when I purchase it on the bottles.

Writing those two dates lets me make an informed decision about the efficacy of the product before I decide to use something else or grab a bottle that is within the “Use By”.

I did not know it had such a short shelf life

I use it in the laundry to keep rotating it out and getting fresh resupply

I would agree, iodine is a better disinfectant, you can clean with it and i dont think it would go bad, my cousin who is a vet and a rancher told me not to worry about the expiration date since its not usually ingested and when bought in bulk it only recently came with use-by dates.
