Cleaning the inside of the frame?

[Kunker]

So the CJ frame is boxed from end to end, and from what I can tell, caked with crap. Any advice on how to clean it out? I'm thinking about a chimney brush and a pressure washer, but any other ideas are greatly appreciated.

I use a hose I cut off one end and force it down the frame rail through one of the holes. If you can get a long bendable chimney brush that would probably work as well

Mini T bought a attachment for his pressure washer. It sprays sidways in stead of forwards. If the stiff is caked on maybe talk to him to see where he bought his. If it's not caked on then just take a garden hose cut the end off and run it through the whole frame like 2Greys said
