I picked up a 2344 powered A unit with very little run time that has been in the box for 50 years. It has a whole bunch of white mildew/mold spots on it. They won't come off with soap and water and I'm afraid to use anything stronger. I was thinking about submersing it in hot soapy water for a few hours but don't know if that will cause the GM decals to come off. Has anyone been able to remove these and if so what did you use.
Thanks as always,
Nick
