instrument/corrosion preventing oils

[stevec]

I installed a castoff ceiling fan that my wife found to be very "flowery" (she's a bit of a minimalist) . It's definitely too "flowery" for a shop but I consider practicality over aesthetics.
Anyway, it comes on with the lights and I've found it to eliminate rust due to condensation.
Often when the shop and machinery was cool and I'd open the door to warmer humid air I could almost see the condensation forming on the machines, now a little air movement seems to have prevented the condensation.
