I’ve had this no name stainless steel conical fermenter for a while now (pretty sure it the original Morebeer one). I got it from the culinarily school I used to go to, when they had a fermentation class. Anyway I made some hard cider a while back when wife was pregnant with our first kid. Problem is I completely forgot that I made it and it was sitting in fermenter a long time year plus I’d say. So I dumped it and noticed these marks in the fermenter. I tried scrubbing with soft pad hot water and PBW. I then did a citric acid bath for 30ish mins drain and let air dry. The marks are still there. Should I try buffing these out and then try to passivate again?
