Lot of good advice here. I also had "inherited" a stash from a friend 11 years ago. Some of the material still smells like cig smoke. I washed it all with vinegar, so that did not remove "all" of the odor. I will now try the Borox, Odoban and ammonia. Some of the trimmings that I was afraid to wash have already been disposed of or donated (sorry Salvation Army)
