Hey, so we were passivating some kegs but we ran into some problems during the rinse. Our passivated kegs would not go above 5.5-6 ph no matter how much we rinsed. The first set we tried we did cold water first around 7 1 minute, 10 30 second, and 10 10 second rinses. We then tried hot water and rinsed for 5 1 minute, 5 30 second, and a few 10 second rinses. Then we swapped back to cold water because the hot water wasn't making a difference and did a bunch more. We tested the pH after every rinse. Many ph strips hit the trash this day.
Eventually we just sanitized about half of them and did 2 30 second rinses first to get the pH to the same level, 5.5-6.
I have three questions. Is there any problems, health or flavor wise, with filling those kegs with beer as is? Should we neutralize the kegs with a mild caustic? Or is there something we are missing?
