For the Canadians in the house:
Canadian Tire brand Brake cleaner works great! The can holds double what the rc brand cleaner holds and for less money. I been using CT brand brake cleaner for the past 10 years, at one time the posted contents and they had matched identical to the rc cleaner of the day... The key is in the product description: LEaves no residue,dries fast,safe on o2 sensors,electric motors...

Seriously, that stuff is horrible, 100% without a doubt. I have given motor spray to people just so they don't use brake cleaner. Yet, Paragon gets banned...jeez..
When i run out of Crown royal, i like some BRAKE CLEANER AND GINGER

It's not so good for cleaning motors, but for parts and bodies, it works great.

R/C racers are so quick to buy "specialized r/c products" that cost 5x times.
the other 30% of that rubbing alcohol is water, btw. So it is not really good if you don't want rust showing up on your parts.

Motor cleaner to me is a convenience. A can will last a long time and I get to watch all the dirt and crap in my motor drip off... And yes, this will dry your hands because the stuff is volatile and will evaporate easily, so I take a glove from the box of 300 clear plastic gloves I have for one hand that I hold the motor in.

But yeah, brushless is an answer to this problem too. I am trying to go brushless asap, (waiting for a used MM ESC or the Sidewinder...)

Soapy water (dish washing soap), followed by a rinse with isopropyl alcohol.

For more thorough cleaning of sealed motors, run the motor at 3 volts while immersed in the soapy water for a minute, then run it again for a few seconds in the alcohol.
The alcohol rinse is important, as it gets rid of the soapy water.

Blow the alcohol out with compressed air.

I've not tried it on sealed 540 motors, but I do it all the time on sealed slotcar motors.

I use contact & circuit board cleaner on my electric motors, It work's great and never had a problem with it. Also I never had any bad reactions to it.

Besides brake parts cleaner being bad for you, all the ones I have used will melt plastic parts. Before you spray that stuff in your motor try it on a scrap piece of plastic of some sort and see if it starts melting away at the plastic. I'm sure ALL brake cleaners don't do that but just be safe and test first.
