We suggest the Labelle 430-00105 Manual Tracking Cleaning Oil for the
sidings and yard tracks that can not be easily cleaned by running a
powered locomotive over them.
It is a 1-oz bottle of our 430-105 Track Cleaner Oil (no cleaning
pads)
Just wet down a folded square of heavy-duty paper towel slightly with
the #105 Cleaning Oil, and wipe down the tracks by hand, until they
are clean, and a light oil sheen remains.
(Also see our Track Cleaning Kit #430-105 which contains appropriate
Track cleaning pads, and our novel twisted cotton swaps for cleaning
switch points set.)
