Watch this demonstration by Dave on how he cleans the wheels of his model train locomotives.

Dave uses the Trix wheel cleaner which you can get in HO scale (OO gauge) and N scale. It is a brush that cleans both locomotive wheels and the track. If required the brushes can be lengthened simply by connecting more than one unit together. This is good piece of equipment to help prevent those dreadful connectivity problems on your track, and to avoid TV and radio reception problems. You just position the wheel cleaner on your train track, then place the loco on the cleaner unit and power up the track. It takes 10 – 15 seconds to clean the wheels.
