Cleaning Edison Price posts

Does anyone know how to clean Edison Price unplated copper posts? I used to use a refrigerant with 3% HCl, and it did the job. I can't get it any more, and every cleaner I've tried since (vinegar, vinegar salt past, Lysol bowl cleaner, etc) cleans nicely, but in a few weeks corrosion returns with a vengeance. With my old cleaner, the posts would just darken with time. Now they get heavy deposits of blue salt. It's as if the post is breaking down chemically, maybe from using that Lysol stuff, which is 7% HCl. Any ideas?

That blue colored salt is not good. It's cuperic chloride formed by the acidic cleaner you used. Have you tried Tarn-X. Its a silver & copper cleaner that works extremely well and is supposed to retard tarnish. And there is also something called Ellanar Silver Polish. A thick pink liquid which also contains a tarnish retardent that works on copper too. Both of these should be easy to find locally. Also "Google" Ellanar Silver Polish for more info.
 
OT: Isn't it CuSO4 + 5 H2O that is blue ? I don't think chloride is blue in color.
Always a knit-picker in the crowd. Trombone's last cleaner contained HCi. That's hydrogen chloride, not sulfide. Being not a chemist by trade, I didn't realize that CuCl2 is brown at first and then turns blue-green when moisture is absorbed. (The way most of us see it.) Maybe later this evening I'll give myself a couple of lashes for not being exactly precise and perfect. :D
