Larry,
"Arm & Hammer" and "Borax" (as in 20 mule team - if you are old enough
to remember) both make washing soda. Some stores also have their own
brand. It's located in the "detergent section" of the store and it is
sold as a laundry detergent booster.
I've "dipped" thousands of parts (including an entire 74 Midget, pedal
boxes, hand saws, flag holders, cast iron spigots - complete with old
brass fittings, hinges etc, etc....) I've been using the process for
over 15 years and have never see a problem with brass, copper, aluminum
or any other metal. Some parts stay in my tanks for weeks at a time
until I get to them. I do remove wooden handles from the hand saws
before I dip them.
I have 2 - 30 gallon tanks and about 3 or 4 smaller tanks. I also keep
a children's plastic swimming pool (5'round) for dipping fenders and
larger parts.
