Copper is great for all sorts of things, manifolds for your cooler based mashing tun, as well as that wort chiller you can't live without. However, copper gets really dirty, really quickly, and I don't think that any of us want all of those oxides in our brew.
To date, I have been cleaning my wort chiller by soaking it in a bucket of star-san, which seems like a waste and it takes a long time to wait around for it to get nice and shiny. Soon I will be building a copper manifold as I get into all grain brewing this summer.
So my question is, what is the best / easiest / fastest way to get these copper parts clean enough for a day of brewing? Would it be better to trade them out for stainless components instead?
