Sometimes after the wash cycle is done on our dishwasher, I start to put away the dishes and notice they smell like bad milk or stagnant fish water. Seriously, so nasty. It happens rarely, but it seems to be increasing in frequency lately.
My H doesn't smell it. He thinks I'm crazy. I've also occasionally noticed it at my parents' house. I can't use the dishes if they have the smell, it makes me gag.
I've tried cleaning the dishwasher with a vinegar or bleach cycle, I've tried messing with the temperature settings, we rinse our dishes before washing, and we do a load every day (so they aren't just sitting in the dishwasher all nasty waiting to be washed). The smell keeps coming back.
