Why do my dinner knives have "rust spots"?
- Thread starter QSis
- Start date
To qualify for the term "stainless", steel must contain a minimum of 13% free chromium. Even at that, they will still discolor, just not as much. Thus they stain less. No, I'm not kidding. 
Or is it 11%? - did that by memory.....
stainless is rust resistant, not rust proof....
is this a recent change? did you also recently change dishwasher soap/rinse?
are they marked with the grade? 18/8? 18/10?
