Jawaguy4 Posted July 30, 2018 Hi, Recently I got some 9V tracks second hand however they reek of cigarette smoke. Do any of you guys know how I can clean them without doing any harm to the tracks. Thanks Share this post Link to post Share on other sites
JopieK Posted July 30, 2018 I would vent it and use alcohol (e.g. IPA / isopropyl alcohol of 'medical' ethanol) for it. Would not hurt your ABS and also not hurt the iron parts. Share this post Link to post Share on other sites

Just to be a pain in the butt - isopropyl alcohol is called "medical alcohol" when you get it for unreasonable amounts of money from e.g. a drug store. "Rubbing alcohol" makes it less expensive but it is still the same … It was just the "ethanol" bit @JopieK: Ethanol is ethanol - and I would rather drink it than rinsing track; particularly in the medical form, always diluted below lets say 40%vol of course. When you do that you may call it Vodka … and I just write these stupid lines because you know so many things about programming and wireless and … and I admire that very much!!! When you want to go much cheaper and maybe more effective with the cleaning: Use some stuff that removes grease. They are sometimes called "Fett und Nikotinlöser". Forget the nicotine part - its tar. Nicotine is a colorless crystalline compound, not the yellowish smeary stuff. There are so many varieties in the stores. The tar on the track (this is the smelly part) most easily dissolves in strong detergents: Just let them sit in a bowl of water with ample amount of detergent added overnight; then flush with water: Smell ist gone.

pirzyk Posted July 31, 2018 @toastie Just don't drink the medial alcohol in the states, it is denatured. One of the lasting effects of prohibition. Share this post Link to post Share on other sites
MagnusE Posted July 31, 2018 Put it in a airtight box with a small bowl with wihte vinegar in it for a couple of hours. The white vinegar will draw out all the odor. Share this post Link to post Share on other sites
LEGO Train 12 Volts Posted July 31, 2018 I usually use mild soap and water and then I dry immediately the washed pieces with compressed air Share this post Link to post Share on other sites

That explains it - I lived 4 years in SoCal ... Well, in Germany "medical ethanol" is of finest quality - uhmm - purity was the word (and you get it in drug stores and the like for an insane amount of money); denaturated ethanol is called "Spiritus" - which cost about a fraction of the medical version. Taxes are high on pure ethanol with good reason of course. Believe it or not but a 2 m distillation column with a 1:20 reflux ratio … upps - this is entirely off topic! I am sorry.

LEGO Train 12 Volts Posted August 1, 2018 Not so off topic my friend ...this is a clarification and a good advice to save money ...save money to buy other lego (but this is another story ) Share this post Link to post Share on other sites
Roadmonkeytj Posted August 2, 2018 (edited) Good old fashion hydrogen poroxide (sp?) I would have to look at the bottle but it takes the odor out of the plastics and brightens them. Just let them soak completely covered overnight (some say 8 hrs in the sun but overnight does just as well) a good warm water rinse towel pat and air dry before use. Tried and tested method.
