    Hi folks!
    Who owns older Märklin models knows the problem: resinification :(

    For time-saving cleaning I have built a loco-bathtub:

    Here you can watch a video showing the usage. Please excuse that it is in German, but you will get the idea:

    Hi Larry,

    That's fascinating. Sorry, I don't understand German, at least not very well. Is this actually cleaning, or could it be a break-in process? When I was flying RC, I had a friend who liked to break in his new brushed electric motors by running them submerged in water. Could that be what's happening in the video?

    Just realized "reinigung" means cleaning. :oops:

    How do you keep from getting electrocuted? Is it just really low voltage, or......

    I recall a Marklin Workshop with Ken Brzenk who was the head troubleshooter and fixer of Marklin America many years ago. In his description of cleaning a Marklin loco he stated that the brushes should be removed before using a cleaning solvent as the graphite in the brushes would soften/deteriorate over time. I have always removed them prior to cleaning.While it seems that the operating bath is effective, I'd want to know if there is any long term damage to the motor. Thanks for the posting.

    Hi folks
    No fear! This is what other model trainers do too, and has been around for quite some time. There were no consequential damages recorded.
    The liquid is called SR24 and is a light oil for steam generators. Since it is an oil, no short circuits can occur. Petroleum should work too.
    A brown standard Märklin transformer is connected to the rails.

    I could say that it is a way to assure that *every* component is lubricated, however:

    Do I want that all over unnecessary chassis parts, leading to collection of dust/debris
    Do I want all that oil over parts that I would touch when picking up the loco, then handle other cars?
    Do i want all that oil between commutator contacts?
    Do I want all that oil within all the motor windings, decreasing heat disbursion?

    Wait . . . I'm thinking of more negative effects.

    KISS (Keep it Simple Stu.... )

    I would be concerned about the effect any oil will have on the traction tires and the eventual dripping of oil on to the tracks.

    Wouldn't the final step in reassembly be to blow dry the loco with compressed air to remove extra oil?

    The oil has a very low boiling temperatur. But that also means it evaporates pretty easily. So it dries relatively fast. Blowing off with compressed air speeds this up.
    Please excuse that the video is in german. The guy tells it all. ;)

    Sounds like it might be similar to transformer oil. I am an electric motor mechanic and we have several types of motors that run in oil. It is low viscosity and relatively easy to cleanup. Need to bring home a quart and check this out on an old Tyco loco.

    What is SR24 closest to here in America?

    One listing I saw says:
    <<<"Model train oil" is one of the absolutely indispensable accessories of any model railway. This rather confusing designation refers to the "smoke and cleaning fluid", the best for 40 years is the market leader "SR24 model train oil"

    The agent consists of a mixture of slightly viscous oils. It is however not a lubricant, but a cleaner! It is excellently suitable for following purposes:

    It can be used as the steam oil in the smoke generators of all sizes and from all manufacturers. Because it evaporates virtually completely, it is suitable for steam locomotives as well as E.g. for floor models on the system such as industrial models with a chimney.

    As the cleaning fluid, it shows particular strengths: either, soak a piece of cloth and wipe it over the railroad tracks or use it as a cleaning fluid in a rail trolley.

    * Who has an ultrasonic bath, can insert there the means as cleaning fluid, it has immediately dirt expectorant effect and no rubber.

    * The applications in the household are little known: who has not already nasty adhesive residue from price labeling and other stickers resented? With the model railway oil remove these residues and the all stickers easily: tired of paint and a few minutes to soak, then you can easily pull off the sticker and wipe away the adhesive residue.>>>

    I bought a bottle. :D Sure seems interesting.
