Cleaning inside of electric motor

It costs a little more but for me it's worth being confident that I'm using the right stuff....

Isopropyl Alcohol is also good to clean motors with, when in doubt .
i have used brake cleaner too, for greasy or over greased motors.
1,1,1 Trichloroethylene was the best cleaner, but that stuff is bad news for living organisms

Be sure to read and understand the label before using any electrical cleaner. It comes in many different strengths, and some will melt plastic parts. Grainger, MSC and McMaster sell a number of different products for different uses.

As an FYI I used some HD contact cleaner on the break away switch for the braking system on the Jeep we tow behind the motorhome. I inadvertently got a can of HD cleaner from an automotive parts store (can't remember the brand). When I sprayed it on the switch it instantly melted the plastic parts together. Fortunately I had a $20.00 replacement is stock, but it was still a PITA to change it out in the middle of a road trip.
 
Plain soap and water...

A bit of dawn in a spray bottle mixed to strength as needed along with a trimmed paint brush for scrubbing.

Place motor sideways at angle and work at lowest point so water and stuff is at lowest point and drain out.

Wet, scrub, rinse with same repeat until clean enough then blow out with air.

Rotate and repeat.

Do one end at a time and let drip dry overnight in a warm place.

I have it apart. both endcaps are separated so I can change bearings, the armature is out, and the stator is still in the frame which is of course open. The endcaps are not a worry, nothing there but metal to clean. The inside of the frame and stator is covered in black dust, as is the armature.

In the late 60's we used trike (TCE) in an overseas materials test lab (quonset hut) as a solvent in ASTM testing and for cleaning the lab glassware.

Mr. Oh, as he was known to us rotating GI's, was the career GS lab tech and we used to tease him because he always wore a gas mask and rubber gloves when going near TCE. We thought that was so wimpy.............................
