I use both HobELube (a Woodland Scenics line) and LaBelle for lubricants. I don't know that there is really much difference between brands. I usually buy sales, specials, or lowest price.
For cleaning locos innards: isopropyl alcohol,, 91% strength if I can find it, 70% if not. For exteriors: a soft makeup brush. For track: denatured alcohol.
