This reminds me the of the John Roskelly story of how he had a pee bottle accident high on K2 and soaked his warmest sleeping bag. The expedition was retreating so it wasn't a biggie. Unfortuantely, the bag stayed in its stuff sack at home instead of getting washed. The bag went along on the next climb, which was Everest. When it it came out of the stuff sack, Roskelly had a rude surprise. I heard he tried airing it out, rubbing snow into it, etc. to little effect.
