Can you let us know if any of these strategies work? I might try doing the same....it's been almost 2 weeks now and it still smells though not as bad (I smell it when it's about 5 inches from my nose).
So, I did sun the bag for a few hours which didn't really do a whole lot so I just went ahead and conditioned my calf bag and it works!

But I'll have to see whether its long term or temporary though.
