General Science / Can knives be dulled by dishwashers?

I was looking for the answer to this after so many chefs advising me not to put them in dishwashers. I found this about hot water: Even “”stainless steel” can rust if it is put together with steel wool into a sink. The sink and the knife blade will rust! Use a pad of brass wire (Goldilocks) a 3 M green pad or a plastic scourer to clean the steel. Avoid submerging the blade in excessively hot water as the edge (which is only one micron thick) will change its temper and become brittle. After the first stroke, the brittle edge will break and the knife becomes blunt again, needing to be re-sharpened
