After reading this thread I had to test this cleaning method on a couple of my motors, and the water did get filthy. Haven't tried running them on the track yet, but it will be interesting to see if there is any difference.
I am unsure about Scalextric "Sport" motors, should the wrapper around the motor be removed before cleaning?
