My wife ran my one of a kind, handmade, tamahagane steel knife through the dishwasher. She load and unloads the dishwasher now, but she hasn't run it since.
surely she's attacking the wrong problem? the issue wasn't that she ran the dishwasher in the first place, it was that she loaded the wrong item into the dishwasher.
if this story is true, then she should avoid loading the dishwasher. running it or not is immaterial.
