Pro tip: if your clothes say 100% merino wool or whatever, this is only about the fiber, and they may still be covered in plastic from the "superwash" process (for example, almost all merino wool is)

Oh, so that's why my fancy 100% Merino wool sweaters don't stink like wet dog when wet, like regular vintage wool sweaters? I know there had to something different in the manufacturing process.

Yeah. Also while not a conclusive test, any wool that even suggests it could go in the washer is absolutely heavily super wash processed.
