: " . . . 5ml of vinegar to 400ml of dilute prepared PMDD (for an automatic
doser) will drop the pH 
down to about 4.2 (YMMV), and that is plenty low to stop just about
everything" (from growing)

==>Actually, many, many, microorganisms can thrive at pH 4.2.  Yeast for
example, and about any other fermenting microbe.  I'm glad your mold problem
is gone, but I can't see how the pH could be the reason.
