Jay,
Sorry, galvanized is not a good choice - It actually hinders the
process and can hurt the piece you are cleaning.
I use concrete rebar but any steel will do - iron pipe works great
too. If you are working with small pieces in a small tank - old
stainless steel hose clamps work great and last a lot longer. I've
even used old parts (cracked A-arms, old pedal boxes, even sheet metal
will work). Just make sure the current will flow thru the piece by
filing it clean where you clamp the positive wire to it. And always
keep the Neg (-) wire on the work piece! Never let the positive wire
submerged in the solution always keep the "sacrificial" piece sticking
out of the tank enough to attach the clamp. The neg connection to the
work piece should be submerged - it keeps it clean.
Let me know if you have any other questions... ;)
Kevin
