Why do I get brown water marks on my silverware (mostly knives, but on other things too)?
It was a relatively expensive set that I bought 3 months ago. The dishwasher was bought brand new 3 months ago as well and cleans (and dries) everything else very well.
The water marks almost look like rust, but they rub off to a clean finish.
I get this both when emptying the DW right after it finishes drying and when waiting until the morning to empty it.
