Track cleaning car

Would be a track cleaning car which is dry cleaning the track an option?

No, I have never thought of

No, I have never thought of doing that. I have only used alcohol and paper towel, the paper towel kinda wrapped around my finger as it rides one of the rails. Nonetheless, that idea would not work since the styrene/cement between the rails is slightly higher than the tops of the rails, on the outside of the rails it is slightly lower. But I could maybe use a dry method, but that does not cut the grime to well I imagine, would work for dust. Thanks for your idea!

Ideally...

Ideally the railhead should be just a little bit taller than the road surface. You may want to consider redoing the fill between the rails otherwise no matter what you use to clean the rails you will end up mechanically or chemically damaging the road surface. 

If the railhead is basically clean, you might try applying some graphite to help keep it that way. My railroad does not run very often and I never clean the rails beyond vacuuming and the occasional wipe with a dry cloth. When I notice a trouble spot, I apply a little graphite around it.

"Ideally the railhead should

     I second Bill's suggestion.  A scraper can cut styrene easily to relieve around the rails a bit. Once the pavement is relieved around the rails the styrene can be re-painted and should mostly stay on during cleaning. If a bit of white shows it will just look like concrete. Solvent based paint should not be affected by an alcohol cleaning but if you want to be sure find some epoxy paint. The mechanical rubbing on the paint  is the thing you mostly want to avoid ,that's where lowering the pavement adjacent to the rails helps....DaveB

Thanks guys for the ideas! I

Thanks guys for the ideas! I will check into the epoxy paint. My stryene that butts up along the code 70 rail is a tad bit lower than the rail top, it nestles under the head. But between the rails is a just a couple hairs higher than the top of the rail, this was carefully planned, looks much better, in my opinion, reducing the appearance of the flange ways. SO here is the thing, I guess I NEED TO BE MORE CAREFUL, I can use a small popsickle stick with one layer of paper towel on it and ride one rail; remember one side is the flange way so i have a little room and the other is a tad lower, so as long as the stick is square and 90 degrees vertical as i clean i should be ok. I guess i was looking for an easy way out, very rare to find an easy way while meticulously modeling... 

Gun cleaning Q-tips

I don't recommend using paper towel on track cleaning ever.

In my Run like a Dream:Trackwork book (eBook 25% off right now), I recommend using gun cleaning Q-tips on each railhead independently. That's because the part of the railhead that provides electrical contact is the top inside railhead edge, not the railhead top. Using a gun cleaning Q-tip allows cleaning the top inside edge of the railhead the most effectively -- getting the part clean that matters most for electrical contact.

A paper towel completely misses the inside edge of the railhead (see image below), plus it catches on guard rails, points, and frog wing rails, possibly doing damage to those critical parts of the track. Ditch the paper towels -- don't use them for cleaning track, ever.

 Clean the inside railhead edge because that's where the electrical contact point is!

Gun cleaning Q-tips are great because they are tougher and a have a bit more robust tip than regular Q-tips and they have a longer wooden dowel staff/core, making them very handy for cleaning track in hard-to-reach places, too. You can get them on Amazon:

Good tip Joe. Never occured

Good tip Joe. Never occured to me that the rail contact are isnt on the top.

Nice! I know about having to

Nice! I know about having to use my fingernail or a small notch at the end of my stick that i have paper towel on to get that inside area. BUT those gun q-tips are great, I actually have a couple! But they look different that the ones you shared the link for. Ordering now! The thing is I am just gonna have to be very careful and spend time in my hard areas and touch up with paint every now and then. Thanks for the replies everyone!
