I recall old-time model railroaders used this years ago. I used it (its a very light machine oil) for my old layout on train tracks - it both cleaned and prevented oxidation in a semi-humid basement. I understand it also helps with electrical conductivity. My existing basement is fairly dry but does get humid in summer - dehumidifier helps initially but since it puts out warm air there's a diminishing return factor (warmer air will hold more moisture).
I read that the black grime that develops on tracks is due to the electrochemical reaction between the type of metal rails and type of metal wheels (I had always thought it was from smoke fluid and rubber tire residues - but that's not the case apparently) ~ thus it is a corrosion process that leaves the black crud - which if allowed to build up becomes a cake and prevents conductivity. I am wondering if that's the reason old-time railroaders used Wahl clipper oil - kind of an old remedy that was forgotten by mainstream? Thus, the tracks still need to be cleaned but left bone dry - rather a final application of the oil? I am not sure of all this, and wanted to learn what some wise old timers thought?
