Does any body have good idea how to stop rust staining of ways on my large cnc mill 100" x 44 " travel. It was hauled in winter and got stained 2 years ago .
I steel wooled it & used fluid film on it ,but it still showing rusting this year . I dont run it every day . I can not put dehumidifier in room (open shop area ) .
Does any body have a good answer ??
