Garage Tip - Shotgun Brushes

Recently I was helping a friend do some loooong overdue maintenance on a dirt bike that had evidently lived its whole life without getting near a tube of grease or a can of WD-40. The front axle was stuck in the wheel, which meant we had to take the fork tubes loose to get the wheel off, but after a good soaking with Liquid Wrench, and some gentle persuasion with a hammer, we got the axle out.The next issue was how to clean out the light rust from inside the wheel. It turns out that a 12 Gauge Shotgun barrel cleaning brush works great!. Fits right in, tough enough to get the grime out, and cheap.
