Tartaric Acid rinse stainless steel?

[Rakhal]

I know that after cleaning a barrel with ProxyCarb that I should give it a tartaric acid rinse before putting wine in it. Am I right in assuming that this is not necessary with stainless steel as long as it's rinsed out thoroughly? I just cleaned out a couple of kegs to ferment wine in. After ProxyCarb I rinsed them and washed with StarSan.

Just rinse the keg with StarSan or another sanitizer. No acid rinse needed. I use kegs all the time and just clean and use StarSan.
