Recently dug out my old post war track cleaning car with the little grey bottles.
The fluid has since evaporated since it was used years ago.
Lionel makes track cleaning fluid, but it appears that it is only available in their maintenance kit in a tiny bottle. If there is a larger stand alone bottle, I can't find it
Any suggestions what I can use in my car as a substitute that won't harm it? Very hesitant to use denatured alcohol for fear of fire and harming the plastic.
Will be using this on Fast Track and tubular.
