I was arguing with my wife over which dishwasher program to use. I want to use the eco program because it is most environmentally friendly, but she countered that the long program (3:30h) puts more strain on the dishes and results in them having to be changed more frequently. Also she is attached to her dishes. Therefore she would rather use the short program for 0:30h. I imagine it is difficult to calculate the exact environmental impact of the dishes being used out by the dishwasher, because it depends at what point of wear the person would change the dishes.
But I want to question my wife's premise that the eco program is worse for dishes. It does take longer and the dishes are probably exposed to more high pressure water streams. But my google search shows that most of that time is used to 'soak' the dishes. Furthermore the eco mode can use lower temperature for washing and drying and that is probably also good for the dishes. So my question is: Which dishwasher program is best to conserve the plates?
(I'm new to this stackexchange, I hope this question is appropriate here. Please tell me how I can improve it to fit here)
