Thanks, does anyone know what "pickle" means in this context (below)?

FYI, for those interested in refinishing the grille slats, my plater,
who is
a master, and I have examined two period grilled under magnification,
and
come up with a strategy that comes close to perfectly replicating the
satin
finish.
The SIDES of the slats are raw brass, plated with a thin coating,
which
accounts for the matte satin finish. To approximate this, you can
pickle the
brass in a modern plating solution and plate. However, the modern
solutions
are purer, and the finish will be a tad brighter.
The FRONTS of the slats were stroke sanded, usually very well.
However, on
one of the two original grilles we examined, you could see some
uniform
'faceting' at the top, where the curvature is a little more extreme.
We are
experimenting with different grits to get the best approximation of
the
original graining, and a fair match to the sides. This is quite
apparent
after the original plating has been stripped. you will see raw brass
surfaces on the sides, and faint grain lines in the front surfaces of
the
slats.
I can vouch that both grilles were old. The one from our car had been
replated, and the corners of the grill slats were rounded. The other
had a
relatively intact factory finish. My plater is going to refinish the
less
intact grille and will be applying the foregoing. He will pickle the
slats
to get the proper matte effect on the sides, then stroke-sand the
fronts,
taking out the polish and at the same time correcting the former
platers
rounding. If the results are pleasing, I will update the posting.
The plater believes that, contrary to notions of 'annodizing' or other
specialty finishing of the grille slats to get the mat finish, it was
the
factory's expedient finishing technique that accounts for the matte
finish,
and that a regular chrome plating was applied. In other words, its the
finishing of the surface metal, not the plating process, that accounts
for
the final result.
