I've never had plastic safe electrical contact cleaner damage the coatings on any armature or field coil winding that I have cleaned. Full disclosure- I typically do this with sewing machine motors and not vacuum motors since that is what I have mostly worked on. I'm old to sewing machines, but new to vacuums LOL.

I would start with compressed air and a variety of brushes before I would consider any cleaners or solvents. If you go for cleaners, be very careful in your selection. Many cleaners can damage the insulation on the motor windings and if that happens, the motor is gone. | ||

Take out the brushes Dissassemble and like Reggie said, run it thru the dishwasher, it will be as clean as brand new! | ||

Dishwasher... I suppose it makes sense. Just be sure to let it dry thoroughly in a WARM place for a LONG time. Moisture left in the coils, especially old coils, could cause minor shorts that'll degrade the motor. The top of a tall shelf in a warm room for a few days should do the trick.
Compressed air would be my first choice. Failing that, brake cleaner is fine, but just beware that some brake cleaners have high acetone content, which would be a no-no, as acetone would probably dissolve the insulation on the magnet wire. Unfortunately, cans of brake cleaner very rarely straight-up list their contents. I believe acetone is more common in the 'non-chlorinated' type. That 'chlorination' is not bleach, btw. It's like perchlorate or something, don't worry about it. I would also beware of high alcohol content ones - they're pretty rare, though - because I'm not sure if it's methanol, which is also a pretty harsh solvent. Anyway, the best way to know for sure is to spray some of the brake cleaner and smell it. Acetone is pretty easily identifiable by nose. Or alcohol. Advance/Carquest Wearever brake cleaner is usually what we use in the shop, it fits the bill. | ||

There is special spray to clean electrical contacts and parts, no need to bodge together cocktails of hazardous nasty chemicals. www.amazon.com/CRC-05101-...
I would never use a dishwasher on any electrical components. Hard water and mineral deposits as well as soap residue from the washer can all sit on and damage the motor, it can also soak into wire insulation and you'd never get the wires dry. I still have hard water stains on my house windows from the lawn sprinkler 2 years ago, tried everything aside from a pressure washer to get them off the glass. It's very hard to remove. | ||

Thanks Madman, actually I have a pretty long metal tube I've used a few times to unclog vacuum cleaner hoses, but I couldn't figure what I could attach to it to rub the inside of the hose. I didn't even knew a dryer lint brush existed...it probably can be found in dollar stores or Wally Mart ? | ||
