It would definitely be washed until the smell was not detectable...drought or no drought...even if it meant washing outside in big totes...WITH VINEGAR too. No one said you had to wash ALL the fabrics in one day - sort them by lights and darks - leave in bags until you have the chance to wash a load until the smell is gone. It may take you the rest of the year but at least the fabrics will be ready to use.
I personally don't think any spray will get rid of the smell. It has to be washed out and luckily it's fabric and it can be washed.
Best of luck
