After getting some sought-after advice and reading a very good article in Model Railroad Hobbyist about track cleaning, I purchased mineral spirits to clean my track and Wahl clipper oil to topcoat the rails.

Both the mineral spirits and Wahl oil are what’s called non-polar solvents. Non-polar means that the solvent prevents micro-arcing which creates dark powder-like gunk that inhibits good electrical contact. So, between both products, I should be good for excellent operating performance.
