So I have a copper immersion chiller that was looking nasty so I decided to soak in a water and PBW soup for a few days. When I went to take it out today, this is what it looks like. Green water and the chiller is "blackened". Reviewing PBW website, it says its safe to use on copper for soaking purposes. Any thoughts?
How do you post photos here too? the Insert Image wont work for me.
