A very dear friend of my parents (in their 80's) gave me what was left of her quilts/quilting projects that her mother had. They had been in storage in her basement for a lifetime. The 'fragrance' from sitting boxed in a damp basement was finally eliminated by letting them all sit overnight in a big tub of luke warm water and Oxiclean (and a cup of white vinegar), followed by a clean rinse by hand and hanging out in the sun to dry.
