Cleaning the AC return on an Airstream can be a real pain in the neck. Luckily Phill from NOLOX has a kit that can help with that. He includes everything needed to convert from the self tapping screws used from the factory to a thumb screw with a backing crush nut so that there is something to thread into.

The process is pretty straightforward and simple, but we'll walk you through it anyway because it is fun to do!
