Oh, I'm glad I don't work in the oven business. We're just starting a stealth startup that's revolutionizing dishwashers, and the prototypes are amazing. They use less water, less detergent, and this weekend we're hoping to solve the last remaining issue: occasionally, they break glasses.
I achieve the first two goals by simply scrubbing+rinsing dishes after most uses and letting them dry. No glued-on food to go gnarly. They go thru the dishwasher once in a while. It's my personal strategy for being eco without getting food poisoning, but I've never seen a paper that evaluates this method in comparison to more-typical workflows (i.e. in-sink wash-using-soap or in-dishwasher wash-using-soap).
