All instruments used on prion pts must be destroyed dead stop. They don't even get reprocessed/cleaned. Place in a bio bag and send them off.
A few years ago there was an issue with this in Germany
Nuke it with lye. Nothing survives lye, even nonliving germs like prions.
Problem with lye is it may cause pitting in metallic surfaces which is a problem because it gives bioburden something to grab hold to, thus harder to clean. Not only that but some sets contain a mix of metals and lye can cause those coatings to be removed.
