Put the sprayed on fabrics in a large plast heavy duty garbage bag. Add one bag of charcoal (not the pretreated kind to lite quickly. Close the bag. Set out in a sunny location for a couple of days. After the first day, go and move the charcoal around in the bag and close it back up. Let it set for the second day. After day two, remove charcoal, shake out the fabric and wash using one of the methods listed above. You can fold each piece of fabric wrong side out before loosly tossing in the bag. That way the charcoal stays on the wrong side of the fabric, but it is suppose to wash out.
