Japanese Wheel Cleaner for N Gauge
Above is the box for a nifty little item I picked up from PlazaJapan on eBay. Its from a Japanese manufacturer called Tsugawa Yokou, and its an interesting, simple, and seemingly very effective device (and did not require any soldering or decoder installation! :-)).
Below is what you get, and although all the materials and instructions are completely in Japanese, its not that hard to figure out! Plug the two alligator clips to a power source and start cleaning!
For only about $20 USD, this is a pretty cool device. I haven't used it a lot yet, but I expect I will. In my experience, I have really wanted an easier method of cleaning wheels for a long time (I always hated to put dirty wheels on 'just cleaned' track! Arg!)...this seems to do the job!
Below is a short video showing it work. The wheels basically sit on a foam material with enough conductive material in them to transmit power to the locomotive. Cool, huh?
