Ta! Ta!

That has been what i have been trying to figure out through my guesses as
to the mechanism. You just cannot get to 90% unless there is something
working beyond what you would expect.

Still think it is dead. Just too hard to have that as the only way that OA
works while all the other Acids of the group (Lactic, Acetic, Formic, and
even Oxalic as a spray or dribble ) do not. At least I have seen nothing
that says they only work through the foot pads so why only OA vapor?
Occam's razor.

It is contact. BTW, that includes foot pads but they are just another point
of contact, not exclusive.
