Default nitric acid to passivate

I need some nitric acid to passivate some stainless. Anybody know of a
common local source? I see my favorite McMaster Carr don't have it.

For example, you cab buy hydrochloric acid as muratic acid at any hardware
store. or phosphoric acid as "Lime Away" at any farm and fleet store or
sulfuric acid as battery acid at any auto parts store.

I see citric acid is also use to passivate. Know a local source for this?


I get my citric acid in the local pharmacy.
