I have done 1 batch in my new-to-me, used-once-as-a-turkey-fryer Turkey Fryer. I did nothing to season the pot before the brew, but I figured I should get it right. I threw some PBW in and let it soak (2 days, I was busy). Now there are 3 distinct colors inside the pot, in rings.
One is a silver, the same color as the outside of the pot.
One is a light brownish color.
One is a single green ring, I think at the level where the wort would have been boiling, although I'm not positive.
Basically, I want to get this prepped for my next brew, and am not sure which is the right color, or how to get it all prepped correctly. I think the brownish color is the oxide layer, but I've never used aluminum before. Any tips to get this all ready to go (and pacify SWMBO that the heavy metal won't be harmful?)
