This would probably work to get the smell out, because a long time ago I got the smell of cat pee out of an article of clothing by soaking in the washing machine in warm water with about a half gallon of vinegar added to it. Then I added laundry soap and actually washed it that way. After the rinse cycle the clothes smelled like vinegar, but then I did a normal wash cycle with laundry soap and no more vinegar, and all was well after that.
