No the abrasives will dull it as well. Also the chemicals in fish detergent will over a long time negatively impact the finish of stainless steel.

What abrasiives? What is fish detergent?

I'd be happy to show my polished stainless steel knives with the hard plastic handles to anyone. After at least 25 years of going through a dishwasher they still look new.

I guess it depends a lot on how one loads a dishwasher

Sorry, I should have split up those thoughts. They can impact the finish of polished stainless (like pots and pans). It is very detergent dependent though. Some have bleach, some don't, for instance.

Which dishwasher detergents contain bleach? I couldn't find any brands online that do.
