Hello Thor,
Thor: sorry about your fire, awful to see your Emco and other tools in the state show your pictures. I have an old Compact 8 myself and would not like to get it destroyed.
DC: Various parts of lathe Compact 8 were stained. In some places the bus, after cleaning with steel wool, I tested rubbing half a lemon, but not as previously cleaned the oil, I find that lemon produces some effect. I have to try later when I start cleaning around. I'll use those occasion to replace the leadscrew and nut with new ones I have spares since 1982.
Thor: From your pictures it seems your cleaning process works, but the loss of work I guess.
DC: Yes hard work. I used turpentine and propanol and it seems I'm allergic to one of them. Probably allergic to propanol that I have used to clean some surfaces instead of turpentine.
Best regards
