I recently made the decision to go AG. I purchased the necessary equipment including a copper immersion chiller from an online retailer. I won't way which because it is not about them. The thing is it arrived with some oxidation spots on it, flaky white powder hardened to the straight section before it starts the coil. Not very much, just a few round spots the size of an eraser head and another spot near a weld which holds the two tubes of the "neck" together. My question, is this to be expected? Should I just clean the thing a move on? Or was this IC somehow improperly stored at the vendor? I might be over-reacting (that's what SWMBO says) but it was a good chunk of change and I just want to make sure I got what I paid for. Thanks for all your comments.
