Terry, I had one of these for years and used it with minimal success (finally sold it at a local train show). I clean the wheels on my Bachmann GE 45-ton and Rapido GE 44-ton locos using the [old] tried-and-true method of a 'soaked' piece of paper towel on a powered track (I use my programming track). After allowing the wheels on one set of loco trucks to run on the wet toweling I then 'burnish' them off on a dry piece of towel (ditto for the other truck). This, coupled with monthly track cleanings, allow my locomotives to run flawlessly. Oh, I use inox (a great Australian product) as a cleaning agent. ///Ray
