2 thoughts come to mind.......put them in sealed containers with Damp Rid or unwind them and soak in the sink in water and white vinegar. Rinse, repeat, rinse, hang to dry. If they still have the odor, keep doing the vinegar soak til it's gone. Unfortunately, the only way you'll know is when they are dry.
AND....be sure to put this in the ebay seller's feedback!
