This practice will cease forthwith! Thank you for a quick reply on
something that I should have thought of before.

My deflasking experience consist of exactly one flask, but . . . The
person I purchased the flask from recommended using a fungicide when
deflasking. Also, since the flask was shipped through the mail, it
arrived in a jumble. I figured the mildest fungicide possible would
be a cinnamon powder extract made with plain water (rather than
alcohol). A worst it did no harm.
