Yes coin collectors never polish the coins because it decreases the value of a coin, and if you have a valuable coin that you want to submit to the coin grading companies, they will not be able to grade the coin, my friend has a story of his grandfather who had Alzheimer's disease and one night he cleaned all his 20 Dollar Gold Pieces, all of them very old 1-ounce gold coins, cleaning them with Brasso, a Brass Cleaning Product......oh no!!!
Anyway, then subject of coins set aside, if the spoon is so tarnished that the hallmarks are difficult to read, and the tarnish pattern looks like a lump of coal, those are the spoons which should be cleaned, and then it forms a new tarnish pattern as the years go by.....
I think it just depends on the specific piece and the specific tarnish pattern, to be evaluated individually......
But I would prefer to see tarnish rather than that "dip chemical" where people dip their spoons, and the spoon is unnaturally, artificially shining....
Polish the silver by hand with a highly-recommended product, and then use a silver polishing cloth afterwards......
