Even if one doesn’t shower for a week taking a wet warm soapy washcloth to the armpits and genital areas would do wonders. As for stinky clothes take a hot iron with steam to them to take out the stink. Better yet regular bathing and washing of clothes are highly recommended.
the trick with the iron really does not work.
we lived in Africa, and the folks that had freshly pressed clothes smelled like BO and spray starch.
Any brand of baby wipes are also effective with less mess and more covenience, just don't forget the feet for those who take their shoes off in flight. Of course, putting the same smelly clothes back on will negate the effort. Baby wipes are at the top of the request list for Care Packages heading to in-country forward operating bases.
