Hi, I wanted to ask how do you clean a car's brush motor after driving in mud and sand with a monster rc?
Is flushing the engine with water a solution?

brush motor clean
- Thread starter rccaflyinair

I don't know if water is the only/best solution but I have cleaned brushed motors with water a few times.
I take the motor out of the RC to clean it. I hold it under a tap and run water over it to start. Then, I fill a plastic yogurt or margarine container with water. I have a power system I've put together that uses four (4) AA size batteries which gives me 6.0V and has a battery terminal that matches the pins on the motor. I put the motor in the water and connect the batteries to the motor. If the water turns to mud almost instantly, I'll dump the water and start again with fresh water. I'll swap the motor leads around to run the motor in the opposite direction. I may have to do this more than once. When the water remains clear, I'm done. I'll use compressed air to blow the water out of the motor and I try to make sure it is completely dry. Oil the end bell bushings/bearings and connect the motor to the batteries again to spin the motor up for a minute or so.
As I said, this might not be the best solution but I feel its better than running the motor with all that crude in it.

My process:
• Pull the motor
• Blow out with LP air (~ 30psi), both sides
• Spray electronic motor cleaner through the motor until it runs clear, repeat from the other end
--- Wear gloves and and eye protection. Have something to catch the spray (the spray will evaporate overnight)
• Blow out with LP air again, both sides.
• Let the motor sit overnight.
• Just before you install the motor, put a drop of light machine oil on each bushing/bearing, giving the motor a spin to work it in.
• Reinstall the motor.

There is RC motor spray. I never bothered. Water will work too, but ensure you it is dry and the bearings/bushings are re-lubed. Again, I never bothered because brushed motors are so cheap.

The trick to using water, is to immediately chase the water out of the motor.
Compressed air, 90% (or higher) Isopropyl alcohol, more compressed air, lube the bearings/bushings immediately after.
Strongly recommend NOT to have power and the motor running when hitting it with alcohol.
