Maybe I should buy some alum, before they ban it like every
thing that works?

How long does this take to work, Paul? I just mean order
of magnitude or
so -- hours, days, or what?

Depends.
#70 drill bit in a 16g watch plate will take about 10min.
Busted 1/4 20 tap in a through hole, maybe an hour or so
until it is loose
enough to wiggle out.
His job is probably have to sit for hours. He might have to
take it off the
hotplate at night and start back in the morning.
Because it is such a small, deep hole, the tiny amount of
solution in
contact with the drill bit will get depleted right away.
