I'm very close to assembling a 10hl brewhouse. I know the stainless is going to need to be passivated. Though I understand the need to get the oxide layer back to the tank walls...I am not certain about a few things.
1. Can the Nitric/Phosphoric blends we see from various suppliers adequate?
What percentage of Nitric needs to be in this blend. What temperature is ideal? What is the appropriate length of circulation? Rinse?
2. Should I be concerned about running this solution through the heat exchanger? Is it going to harm the gaskets?
3. How can I tell that I have succeeded in repassivating?
Thanks!
