Following heavy duty gigging or sessioning, I always take my instruments and their cases outdoors and purge the smoky residues by blowing as hard as I can half a dozen times into the soundhole (no rude jokes please!). This certainly reduces the residual smokiness in the cases and instruments although probably doesn't completely get rid of it. But it is at least free and avoids the problem of getting noxious substances in contact with your pride and joy (again, no rude jokes please!). I always keep the cases shut at gigs.

This method will certainly be used several times at this weekend's knot of gigs!

P.S. Of course it doesn't help with the physical damage to the lungs from the often very smoky atmosphere at pubs and other venues (I have never smoked) and this is one reason I gig a lot less now than the several times a week I used to. But there have been whole threads on that subject before!
