Is there an easy way to degrease and de rust a K frame?

Interesting comment, Rusty Rat Rod. I found in the end there is no easy way, at least not around where I live. In the beginning, my definition of easy was a hot tank or an oven like Harrisonm mentions above to avoid lots of scrubbing with a wire brush by hand.
This hobby ain't "easy" as a whole.

I guess you could let somebody else do it. But then it ain't easy on your wallet. So there's really no easy way. lol
