Just read on the University of Missouri Extension Service website that the only way to get rid of the smokey odor from textiles is through a process called "ozone treatment" (an ozone generator is used). There are supposedly no chemicals or cleaners that will take the smokey odor out of the fabric. It has be to neutralized and only ozone can do it. They also say that any perfumes, Fabreze type sprays, laundry soaps, etc., will not do anything to remove the odor that only the ozone treatment can do that. I'd bet this is an expensive treatment. What your DF needs to do is tally up the amount she spent on her stash and add it to her claim for reimbursement on the insurance. I'm not sure there is anything you can really do to salvage the stash short of professionally ozoning it.
Hope this info helps...
