One of the simplest ways to clean a motor is to immerse it in water. That's right, water. Run it under water at low voltage for a few minutes and check the condition of the water. Filthy, ain't it? You don't need solvents because it is not the solvent that is cleaning the brushes and comm. It is cavitation. The same thing that eventually chews up boat propellers. Cavitation is what happens when a spinning surface revolves in a liquid, especially if there are fixed barriers (the brushes) riding against the spinning object, or irregularities in the object's surface (the comm segment gaps). In essence, a negative pressure is formed directly adjacent to the spinning object (comm) and especially behind any barrier (the brushes). This literally creates microscopic vaccuum bubbles which subsequently implode. Multiple implosions happen at high frequency, creating zillions of tiny shockwaves that assault the surface of the comm. THAT is what cleans it.
Also, running a new motor under water for a few minutes is one of the easiest ways to break in a fresh setup.
You can dry it with heat or just let it run in free air, but you do need to dry it out. Then be sure to oil appropriately.
Don't believe it works? Take an old junk motor and try it.
