Cleaning frames

[Dale]

What would be the best way to restore the finish on older enameled scopes? Corrosion on steel parts.
Frames and stages, etc. These are American Optical. I am not even thinking about repainting, just
intensive non-destructive polishing.

I wouldn't try anything on a microscope to remove rust. I hope you didn't buy it! If not, walk away.

If the outside is in such poor condition who knows what the insides are like

AO's usually have problems with rusting on the securing screws and exposed bare steel metal surfaces. I use a toothbrush dipped in light lube oil. For heavily rusted parts I use a small brass wire brush (don't use on chromed or plastic surfaces), dipping in a light lube oil and bushing lightly and then rubbed with a lightly oiled cloth. For painted surfaces, I use dishwashing liquid in water and cloth for dirt and grim, and using a toothbrush in cracks, corners and hard to reach areas. For troublesome assay inked numbers and sticker residue, I use a cloth with acetone. Don't use the acetone on other ink painted areas or plastic surfaces. Then rub down the whole stand with a lightly oiled cloth and then a clean cloth. Make sure all optics are off the scope when you do this.

I was warned to go lightly. Charles, I printed your reply, thanks. Have much research to do now.
