As a onetime CO of a C-130 squadron and insistent on clean flight decks and no beverages ever to be passed over consoles I had some hoses made up having an end fitting which plugged into the astro compass receptacle.
Pressurisation to atmosphere made a very poweful vaccuum cleaner. Pity it's not a standard fit. Right seaters even took to doing the cleaning at home!!
Loadies and engineers all wanted their turns!!
But never ever try to throw a paper bag of prawn remains out of the para door. Most come back inside, swirl around and stink for weeks.
