A bit of a thread hijack, but while some high streingth acids can etch or destroy stainless, most SS cleaners are a dilute form of acid. In my experience, I have never seen vinager have any effect other than help remove corrosion and salt residue, but a chemist would have to be the one to discuss wether is has any corrosive effect.

So I think the trick is to just make sure the muratic stuff stays away and you will be fine.
