I would like to see a couple of other folks step up with some unique ways to clean guns/gun parts.

Ultrasonic would be nice to see. I've only dabbled in it a little.

Having someone discuss how/why and what to clean would be useful to, especially how shooters of lead bullets face different cleaning that those shooting copper jacketed, why cleaning the barrel reduces accuracy, etc.

Some of the store bought methods vs non-store bought.
