Hi! As a clock restorer also, I use an ammoniated brass cleaner first. I just soak them overnight, and then rinse. 99% of the time they are very shiny and bright. The other times, they just require a light buffing on a wheel with rouge, or even a light hand polishing with Never-Dull from the automotive store. I do this will all brass piano hardware. Usually it removes any lacquer or shellac also. The cleaner, (I use L&R), is available from Merritts' Antiques on line and others like LaRose. Your local clock tech should sell you some also. I also use it to clean and degrease player piano transmissions. Don't use it on any parts that contain pot metal: it will turn everything black. Hope this helps.
