This is It.....
5 gal of water can get it done - i warmed mine with the sun
for ambiance - & rhythm keeper **
a likkle soap (my piggies get the good Dr. Bronner's peppermint - others work as well)
bicarbonate (not required)
hands (required for this method)
Pre-rinse to get the gunk out, soap, lather and scrub to work the funk out, hit those hard to get spots and rinse away the funk.
Rinse well. hang dry (outdoors pref.) This method was used with a solar shower (5 gal.) during the early evening (warmish water)
after working on a very dirty (literally) construction site...day in and out for weeks on end. Any built-up funk that remained
at the end of the trip (and there was some) was quickly and quietly terminated with some Oxyclean soak and extensive rinse.
You might want to put the JB video on repeat, but it shouldn't take mush longer than twice
**I also think this would be a heavy dub to run adverts around for the FF brand. Mashup some stage clips of the Godfather in FFs cgi style....
sorry for the inner Dimbleby...
