A good argument against 3% or 5%. However, the fact that H202 decomposes over time, losing it's efficiency along the way, is simply a fact. It's
no more a
problem than the fact that uneaten food will not keep indefinitely. 35-50% will remain useful and effective for several years,
unless stored in direct sunlight. Chances are you'll be able to source more in the mean time.
Shoot, if you've got 15k hanging around before catastrophe hits, and you're that worried, you can by a ready to operate still that will produce
98-99% H2O2 by the ton.
Or... Sodium Percarbonate will last about as long as you want it to. Mix a
tiny amount with water... you get usable H2O2. You probably have
some in your laundry room already anyway in the form of Oxi-whatever. Or, you can buy a pound of the pure stuff on ebay for $5.
