I'm still getting dark residue sh*t on my keg walls that's getting into my beers. My first time serving from the keg was at a party last weekend and the beer came out blackened and tasted metallic.
After sifting through many threads, I still can't solve the problem. Here are the steps I've taken so far:
1) On receiving the keg many months ago, it was disassembled, soaked in PBW overnight, scrubbed thoroughly with a kitchen Brite pad, rinsed and left sitting around with the lid loosely on for months. Not surprisingly the first scrubbing produced lots of black residue.
2) Pre-kegging the beer, the keg was rinsed with water, partially filled with diluted starsan, shaken multiple times and left overnight.
3) Post the party humiliation, the keg was soaked with PBW overnight, scrubbed down with a Brite pad and rinsed. The rinse water was still black (see photo below)!
4) After going thro many threads again, I then scrubbed the inside walls again with the Brite pad, rinsed, sprayed on 50% solution of concentrated phosphoric acid multiple times over a period of about 2 hours and then rinsed with reasonably hot water. After it dried, wiping the walls with a tissue still produced the black residue (see second photo)!!!! Aaaargh.
Shouldn't the keg be passivated from just sitting around for months?? Why wouldn't it be passivated after so many scrubs and spraying on the acid??
