So I was cleaning and left some black, liquid out, keg connectors soaking in star san. I forgot about them for about a week and opened the bucket they were in and the metal portion has turned blue and the whole lot smells like some metallic smell.
Are they toast or can they be cleaned? I'm soaking them in pbw now. I don't mind buying new ones but I hate to let plastic go to a landfill so my descendents can find it 35,000 years from now and say, "What kind of idiot left keg connectors in sanitizer for a week?" Not sure why this happened.
