I recently replaced some lighting fixtures on two houses owned by the same person and all the old exterior lighting fixtures were the same, and I kept them, all fourteen of them. These are coach style, brass fixtures and large in my opinion. They range from about 12" tall to 28" tall. Of course they have tarnished over time and I would like to make the look better. Does anyone know of any chemical dip application I could mix up and use to clean this brass? I'm not into the thought of hand polishing all of these. I'm thinking (UH-OH!) that I can remove the electrical parts and glass and just dip/soak them in some solution, dry them good and put a coat of clear on them. Any suggestions? Thanks, David
