Is that the stuff that's supposed to passivate the SS?

I've also had good luck with 3M's metal polish and restorer, but I like to
use Nevr-Dull first if possible.

Check out WhitchNox. Made by Witchard. Wipe it on with a cloth, let set
for 30 minutes then hose it off. Maybe a quick polishing after to make
it
really shiney.

Doug's right, though it's spelled "Wichinox." Contains phosphorus,
supposedly. Works for me.

I use a weak solution of nitric acid to passivate stainless. (I don't
remember, off hand what the mix is. I just keep about 5 gals mixed in a
plastic drum and hang the part in it for a few hours.)

A welder friend has a jelly solution that has nitric acid in it. He brushes
it on a finished stainless weld and lets it set for a couple hours then
rinse it off. Really cleans the weld effected area and never seems to rust
afterwards. Very expensive (about 15 bucks for a half pint jar.)

That sounds like WitchNox. It is a bit expensive but it goes a long way.

Citric acid 910%) works as well as nitric and is much safer - see -
