To be sure you know somebody with a half decent air compressor and a blow gun,...if not, your local mechanic should have one,...( I’d hope) .....snatch off the brush plate and blow that rascal out,....everybody is kinda overthinking this,....it ain’t that big of a deal,.....I’ve blown out hundreds of manga traction locos filled to the brim with god knows what stuck to the magnets, and wheels,......this is about a 20 second job,......
