<DIV>Chris,</DIV>
<DIV> </DIV>
<DIV>I have never done this (yet) but it is only for brushed motors. It helps
to seat the brushes to the commutator, without building up heat and without
the worn material staying in the motor. For the small can motors, hook it up
to a D cell battery, immerse the motor, and let it run until the battery is
dead. The water will be dark from the material worn off. Dry it out very
well, and lubricate the bearings.</DIV>
