[QUOTE=Austin W Hogan;7017]I wipe discolored metal parts with Hoppes, and wipe them with a cleaning patch. If the patch becomes red or brown I repeat, then grease the part thoroughly. Repeat every day or two; if the red or brown persist give the piece a few strokes with a file card and repeat the Hoppes and grease routine. It is amazing how much finish remains under soft build ups.
Best, Austin- Austin- I believe many jewelers use amonia to clean jewelry- would that work if diluted with water and Not hard the case colors like Flitz and Brasso might?
