Stainless steel rusts quite easily when touched by other rusted metals….
You even provided an example, in a sink with a cast iron, that required removal with steel wool.
Im not twisting things lmfao, I’m using your own real world examples to show how stainless can and does rust. You have multiple people trying to explain this to you, and you’ve provided examples of it. Yet you still want to stick to your guns eh? Is this what flat earthers are like?
