I wonder how well naptha actually disinfects in comparison to my high expectations of it . (Post-war Lionel's suggested cleaner (not for.some inks)
I'd think the "waste ammonias" would do the most damage really.
Nothing with bleach, some plastics cloud from chlorine. Maybe Clorox II if anything like that( ???)
For all metal cars, I'd go for boiling water, fast and full, forced air dry (hair drier), and recoat; 100% oil wipe or douse 100% in clean oil, drip overnight on a towel and final wipe to run)
