G'day all....quick question as I prep to brew today here in S. Illinois.
Recently I soaked my immersion chiller in StarSan to clean some of the darker green off near the hose connections. I know this residue is somewhat toxic (well, I think it is.)
Do I need to mix up a new batch of StarSan or is my current batch still safe for sanitation today (assuming my pH is still good...I mix withdistilled water and stretch each batch a couple months)?
