I decided to try vinegar and salt, having had excellent luck on brass
before
with it. It worked amazingly well. I made up the solution in a little
disposable
tupperware and put in a handful of tips and stuck it in the microwave for
a
minute to let it get hot again, then simply took them out and rinsed them
in hot
water, wearing rubber gloves. I didn't see any etching or weirdness and
they now
all look new. Pretty surprising to see them go from dark brown to shiny
copper
in a minute.

Great choice! Brass in sulfuric would be a bad combination, so not only is
your system safer for handling, but safer for the products. Thanks for the
tip, Grant.
