I have a Waterbury clock that I just completed the cleaning and restoration of the movement and have fixed a few dings in the wooden case (it looks really good with no refinishing required). However, the clock face itself is dirty, worn, and actually looks like the thin brass overlay is rusting in spots. Picture is attached. I also took a picture of the back to show the thin overlay wrapping around the edge. I have seen many, many comments here about just leaving it alone, and I have no intention on trying to restore it to its original condition. I just want to clean it but am reluctant to touch it with anything without some guidance. The face is obviously paper. Use mild soap on it, or don't touch it? Just leave the rust spots alone or do I need to clean them, or treat them with something?
