Beyond Canon era:

Dirk's sweat tastes of a particular limited-edition artisanal barbecue sauce made with reaper chilies, not that you'd recognise it. Aftertaste of hashimi.

Both incarnations of Roxy are slowly sweating out all the gin they drank in their mispent youth. In a few years time it'll be the vodka.

Meat Jane's sweat tastes of marzipan and cream cheese frosting; Candy Jane adds a sickly touch of fermented Faygo to the mix.

Jake: woodsmoke, gunpowder and whiskey, with afternotes of blued steel and despair.
