FWIW, yes, I read the earlier posts about how peroxide is a waste of
money in the garden, kills beneficial fungii, nematodes, etc. And I

Sara in Atlanta said she stores 35% H2O2 in the freezer. In one manufacturer's write up this is specifically warned against lest it break down. Storage is recommended in a dark cool place like the refrigerator where the loss of potency per year is minor - according to them about 1% or so per year."
