I didn’t say anything about the heat treat or anything, specifically because, like you said, the dishwasher isn’t reaching temperatures where that matters.
I also didn’t try to claim that your detergent would rust your knives. This is literally all just you.
All I said at the end of the day, is that your knife edge is more delicate that everything else you’re comparing it to, and your dishwasher can bang it against things which may chip it somewhat, unlike everything else you’re comparing the knives to.
If i turn off the water while i soap, it takes like 3 minutes to get hot water again after I’m done.
