Ever see a double pane insulated glass door that looks white
and frosted on the inside? That is due to water vapor that
found its way between the panes, and condensed. Because the
inside glass is about as clean and free of dirt (minerals) as
the manufacturer could make it, the condensed (distilled) water
leaches out silicon, etching the glass.
Nature abhors a vacuum.
In the case of putting a teflon coating inside of the bottle,
you want the sides of the bottle to have lots of nooks and
crannies (at a molecular level) for the teflon to mechanically
grip onto... So, it helps to etch it a little bit. HF will do
the job very quickly, but if you have a source of well polished
distilled/dionized water, you can etch it that way as well...
it just takes a little longer.
