Cleaned with vinegar now chalky blue
I have a copper loop and I did the vinegar flush but I went to work and probably just kept letting it run a while longer. Long story short there is now this blue layer on everything. It's faint blue/white chalky crap. Any idea what it is? I cleaned it out of the heatkiller by taking it apart but I don't know how to clean it out of the radiator. Any help I'd much appreciated.
