Polishes vary a lot, I have had metal polishes starting to dissolve paints (like on Elnas), you can't go by random choice, you have to get the right stuff for the job. I lean towards furniture polishes suitable for shellac, or resin type car polishes. On very special machines I would hardly dare anything but gentle cleaning. I allow a few signs of wear and age, I don't mind. I do touch ups of chips and if there are spots where the paint is missing or very worn. A machine should be in bad shape before I do a refinish and complete stripping of the old paint. I tend to avoid too much rust or damaged chrome. I clean off all grime and dirt, usually with a bit of effort, and it takes a few turns of cleaning and polishing before I get there. Maybe a bit of dissasembly here and there too. I poke around with tooth picks, cotton swabs,...
It looks like your machine is cleaning up very well. Any test stiching, or new leather belt?
