I toss the brass in a stainless pan, add water to cover plus another inch or two, put in a couple of spoonfuls of auto dish detergent, and heat them on the stove while stirring with a stiff bristle brush. When things have come to a boil, I transfer them to a strainer and then back into the pan for a rinse. Then into the oven on 200 for about --- 1/2 to 1 hour.
Takes around an hour, and clean enough for me. I try to not get too anal about the shine. Life's too short. jd
