That is great! You should use a brass bruch or one of the new stiff nylon brushes! *Never Stainless! I prefer the brass. As far as cleaning the brass brush when it gets dirty I use CRC *Non-Flamable Brake and parts cleaner. They make both types flamable and non-flamable! But do not get it under your rings, watches on your skin. If you do wash it emediatley. Or best to wear chemical resistant gloves. I just spray the brush with it and the grime runs off. I then rinse it off with hot tap water and let it dry.
