Vinegar should not etch galvinized steel but in and of itself would also be
a reasonable cleaner for cutting oil (it is used in many window cleaners).
It would also help remove scale if you dared to use used pipe.
Primer will give it plenty of tooth.
BTW Have you seen cold galvinizing spray. It is basically zinc spraypaint
and can be used as a primer directly on steel.
