This is my second season with the stainless steel spiles by SapMeister. I was concerned with microbe activity so I talked my wife into running them through her IP. For those who aren't familiar with an IP it is a modern pressure cooker basically.

They did come out noticeably cleaner after an initial soak and scrub.

Anyone have any experience with running spiles through a pressure cooker? It maybe an exercise in futility.
