Hi!
Fairly new to cider and loving it. I've purchased a used corny keg and some other parts from a guy locally. While I was there to pick it up he realized he'd left a kiwi beer in the keg (I don't know how long). There was a thick brown film on inside when I got the keg that didn't come off by rinsing it. I soaked it in a cleaner I'd gotten from the local brew supply store (can't remember if it was Star San, Five Star, or something else - it was just in a little baggie so no label) for 24 hrs in household hot water. Everything looked good so I let it dry, replaced all the rubber, reassembled it, and sealed it. About a week later I opened it and it smelled just the same. I then let it air out for a week and resealed. Same result. Thinking I'd not cleaned it enough I again soaked it for 24 hrs (including inverting it in a bucket of the cleaner), and let it air for a week before reassembling it. Again, it smelled when I opened it. Its a sort of fruit beer smell. Not bad, not also not pleasant, and not what I next batch of cider to taste like.
My fiancee says I "just need to scrub it more", but I feel like there's something else I'm missing. I just read the April 12, 2020 post "Odour in stainless steel". Wondering if I should tried a different cleaning method (if so, what?) or try to passivate the keg, or something entirely different.
Thanks
