I just found a post over on the antique radio forums that said if you have to clean the contacts to not spray the phenolics with deoxit as it can ruin the calibration of the ranges. Well....what's done is done, I guess. I dowsed it pretty good trying to clean it up. Not sure what else one would clean it with, (vinegar maybe?) especially when the shaft/bushing was so corroded inside. We'll see how it works in a few days but I can't imagine the calibration is helped by battery acid either.

...I started spraying it down with Deoxit and it cleaned up well but couldn't break the shaft loose despite dowsing it with Deoxit. I finally used some strategically placed Deep Creep penetrating oil on the shaft bushing inside the rotary switches and under the selector handle on the outside and then just let it sit and soak. I did that a few times over a couple hours and lo and behold, it started to break free! I continued to spray penetrating oil on the shaft and finally got it fully functional and finished cleaning it up with the Deoxit...
