Does anyone know of a good water soluble chemical that will remove years of dirt and oil from the interior of wings and fuselage ?

Check out Simple Green. I'm not saying that's the answer, but it's worth a look.

I did try some paint stripper on few test spots. It does work. My concern is that the stripper will get into the lap seams and may not completely wash out. Whadda ya guys think ??
Phosphoric acid (first step in etch and alodine) will clean up oil film and corrosion and is water flushable.
Ospho is mostly phosphoric acid. I using it for cleaning rust off the bathtub.
I would second the recommendation in the other iteration of this discussion for Dawn, or some cheap shampoo - both with a soft bristle brush for washing cars. Both will cut oil, grease and grime gently. Rinse thoroughly, of course, otherwise you'll end up with a sticky film that will attract more dirt.
Measure twice, cut once...

OK guys, here's what I wound up doing. Mineral spirits. I know, not water soluble. The project was C150 wings that had been treated several times with a corrosion preventative over many years. A lot of caked on dirt had collected, particularly aft of the rear spar. Some places I could reach in scrape the crud off and the vacuum out the clumps. Wings were NOT on the airplane. Dish soap, engine cleaner, WD-40,ect. did not perform well enough. I sprayed in mineral spirits and let soak for 1 hr. I then used a pressure washer with a 90* nozzle to blast out the crud. Not squeaky clean, but enough to evaluate the wing internal condition. Oh ya, mineral spirits does kill your back yard grass.
