Yup. I’ve been obsessed with cleanliness and aluminum part finish at the nano to micro level. Stuff happens very easily to any machined surface when you just touch it with bare fingers. Its incredible how much of this we never care to see.

Like people bring up micro plastics and they ponder and ponder where it could be coming from. Meanwhile they’re scraping stuff off their eggs with a plastic spatula against a PTFE surface. Sure PTFE can withstand the heat, but it’s still very easily damaged by rubbing on it with something else. And this is why we’re all getting cancer early.
