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

I used Superclean today at the carwash. It got a lot more off than I thought it would. It did not get it all off. I will still have to do some wire brush work with solvents. After it is degreased I don't know what I will do. Sandblast and Por -15, maybe powder coat, maybe just chassis black paint. I have to figure out how to clean out and paint the inside.

Degrease and clean may be a challenge everyone has their favorite solvent or other workaround, then usually blast out as much as you can with a pressure washer. Eastwood has adapters for their internal frame coating that allow you to snake the sprayer inside. I've not used it but will probably try it out as I get to that stage.
