For some people, the only enjoyable part of cleaning Lionel track is arguing about how to do it. The rest of us don’t even enjoy that part. Recently I unearthed a decades-old secret that mostly eliminates the need to clean track. Sound too good to be true?

Why cleaning Lionel track is necessary

This little known compound, No-Ox ID A Special, is the secret to cleaning Lionel track, or any other model railroad track, much less frequently.

The surface of the track and your train wheels is never completely smooth. It’s also not perfectly clean. Both of these things lead to imperfect electrical contact. Imperfect contact means sparks flying when electricity is flowing. Sparks pull in dust from the air like a magnet and deposit it onto the track. So as you use your track, it naturally gets dirtier.

But what if I told you I haven’t cleaned my track in about four years? And I got away with it?

An old cure from an unlikely source

Linn Westcott, the original editor of Model Railroader, used to treat his train track with No-Ox ID A Special and stated he knew other people who did as well, and they never had to clean their track aside from occasionally vacuuming up debris.  The Ebay link I provided is the cheapest place to buy it; a 1 ounce tub of it costs around $5 and will last decades. No-Ox ID inhibits moisture and claims to bond to naturally occurring oxides and make them conductive.

This helps break down the vicious cycle of track cleaning. Track gets dirty because of electrical arcing. The spark deposits dirt into the pits in the track. The dirt inhibits conductivity, which creates more arcing and more pitting.

Eliminate oxidation as a source of arcing, and you break the vicious cycle. Once you break the vicious cycle, you don’t have to do much to keep the track clean. Cleaning Lionel track becomes a thing of the past.

The process for applying No-Ox ID A Special

The small-scale guys have an elaborate procedure for treating their track. Since O and S scale/gauge trains are bigger and heavier, you can take shortcuts. It’s a good idea to wipe down the track first but truthfully, I didn’t. If your track is visibly dirty, wipe it down.

Put a bit of No-Ox ID on your fingertip. Rub a small amount along the inside and top of the outer rails and the top of the center rail. If you can see it, you’ve applied too much.

Apply enough that the track feels different, but not enough to see.

After applying, run your locomotives on it to spread the grease around and treat the locomotive wheels. I ran a few of my locomotives for about an hour. I would avoid using traction tire-equipped locomotives for this.

Let everything sit for 24 hours, then wipe the excess off your track. If you have locomotives with traction tires, use a cloth with alcohol or mineral spirits to dissolve the grease. The grease is just a carrier, and after the chemical reaction is done, you don’t need the grease on the track anymore.

And as best I can tell, you only need to do this once. I treated my main layout in 2016 and haven’t cleaned the track since.


You really can use too much. As a test, I applied what I thought was a small amount on a single track section. The engine stalled on that particular track section. After I ran the engine over it a few times, it came back to life.

Even though it takes 24 hours for the treatment to fully kick in, after a few laps, I noticed a difference. Trains always used to slow down on the hardest-to-reach area of the track. They don’t anymore. The speed is more consistent, and I see less arcing.

Marx locomotives tend to arc a lot more than Lionels. But each time I grabbed a Marx locomotive off the shelf and put it on the track, it stopped spitting sparks after a few laps.

I won’t take the layout apart to do this, but the next time I have to take up any track for any reason, I’ll apply just a touch of No-Ox-ID on the track pins before I put the track back down. That will help with continuity too.


I liked the effects of the No-Ox ID A Special so much, I set up a loop of track to use it to treat locomotives as I maintain them. I just grabbed enough curved pieces out of my box under the layout to make a loop and put them together. Then I applied a bit of No-Ox ID A Special on each rail, then hooked up a transformer.

Finally, I grabbed locomotives that haven’t had the treatment before and ran them on this loop of track. After a few minutes, the wheels stopped throwing sparks. I let each one run for 15-30 minutes, then gave another locomotive a turn.

I found that in addition to less arcing, the trains performed better at low voltage. This makes sense; if the electricity flows more freely, the trains have more power.

As I acquire locomotives, I plan to just put a dab of No-Ox ID A Special on each rail, then run the locomotive as part of my break-in process before I try it out on my layout. This is especially beneficial for Marx locomotives. I don’t know what it is about Marx’s driver wheels, but they arc a lot. And I’ve seen Marx engines fail to run, but come to life just by cleaning the wheels. Treating the wheels with No-Ox ID A Special greatly reduces that problem.

I wasn’t sure what to think of the stuff at first, but I figured for five bucks I didn’t have much to lose. I’m a believer now. Cleaning Lionel track isn’t something I expect to have to think about anymore.
