Either your manufacturer used a much better grade of SS or you are sailing primarily in fresh water.
Or...
I found minor differences after cleaning.
I did the full polishing after we got our boat.
Focused on the Jib sheet winch and electric winch which are prominent in cockpit viewing.
We even have canvas winch covers.
Our railing tubing is perfect.
Using these wenches [winches too
] often, keeps them polished, so to speak.
But...
I don't take a lot of guests out either.
I just asked the Admiral if she thought our Stainless needed cleaning [she is a perfectionist on having the boat clean].
Ans: Not that I know of.
Like I said, each to his own definition of "decent".
Polish away...
Jim...
PS: Wenches don't need polishing.
