Hey,

does anyone but me find that their potassium hydrogen phthalate gets
pretty moldy pretty quickly? I've started storing it in the
fridge--how do other people store theirs?

Baking at ~250°F for an hour or so (to drive off water and kill any mold
spores) and keeping it in a tightly sealed glass bottle should stop that
problem.
