tried a baby bottle brush for cleaning the inside area of the wheels...perfect length for reaching all the way to the interior.
plus I figured if it's good for a baby bottle it should be safe for the challenger LOL

I'm always collecting various types of brushes while shopping online or in a brick & mortar retail store. Sometimes I'm not excatly sure what I'll use some of these brushes for and then one day I have a "eureka" moment. ....but that's usually when I discover that my source no longer carries it when I go back to grab a spare. :lol:
