    Tripoli, @zosimas. In Libya, on the Mediterranean Sea. Famous in a song.

    Why would we need an Arabic city to polish wheel treads anyway?

    It's a polishing compound from the Halls of Montezuma. Or was it a compound word in Polish from Monte Hall? Anayway, semper fool.

    Toilet paper will disintegrate and make a mess. Use coffee filters instead.

    How to clean the wheels want the question, should i replace them?

    or have any of you replaced old loco wheels? or do you just toil away cleaning them before and during every op?

    meanwhile i will try no-ox on the wheels. or maybe conductolube as suggested in earler post by mac

    oh, look what i found... http://www.nscale.net/forums/showthr...Oil-Dry-Grease

    Here is an article about conductive lubricants... https://www.nmra.org/sites/default/f...10_clean_2.pdf

    I think ultimately this is all about your grades, the length of trains, number of locos, etc... conductive lubricants work great but definitely reduce traction so it depends on what and how you run.

    Not every op, just if I see the headlight flicker or hesitation. And not exactly toiling. I rip off a square of TP, lay it on a straight section of track, drip isopropyl on one end to cover both rails, pick up loco, set speed to high, rerail it so one truck is on the TP, let the wheels spin, repeat with other truck, toss the TP, reset the speed and re-rail the loco. OK, maybe that sounds like a lot but it takes a minute. And its satisfying to see the black marks on the TP.

    I'm wondering if maybe those ridges help keep dirt from cutting the electrical pickup. Suppose the dirt gets pushed to the grooves so that the ridges still make contact. If that's the case then polishing will make it worse.

    Hmm, if ridges are there for what you say then mine are lacking in that department, maybe I'll look for new wheels
