Hi, nice site. I'm not aprofessional plumber, but do a fair amount of it refurbishing a 100+yr old house. I was wondering if unused but corroded copper sweat fit fittings are salvagable. They were in a wooden box in a celler that typically floods 2-4 times per year. The box rotted away, leaving a pile (30-40 lb) of bright green pieces. I don't want to risk leaks, but I don't want to throw away money either. Is there something to make these servicable? Perhaps some solution to soak them in?
