Hi all!
I have had a grainfather for a while now but have had a brewing hiatus. I find it hard to fully drain the CFC free of water. I picked up the CFC yesteday and realized that it had not drained completely, meaning that there has been water inside it or two or three months. My normal ater-use cleaning cycle is to run PBW at the recommended temperature for the recommended time (I don't remember it off the top of my head - something like recirculating for 15 minutes with 55 C PBW solution) and then pumping water through the CFC to clear the PBW and wort out. So to my question: I don't know what the insides of the CFC are made of (or rather, whether copper comes into direct contact with wort) and I am worried about nasties / verdigris. I am thinking of brewing this weekend and wanted to know whether the CFC is safe to use after doing the following:
1. Run a PBW cleaning cycle
2. Run boiling water through
Or do i need to do something more elaborate?
Thanks in advance. I am a bit worried - especially about verdigris.
