An earlier post mentioned a formula for de-skunking a dog, and suggesting to use it on the fabric. I use "Simple Green" cleaner on my dogs when they have run into skunks. It takes two washings. I have also used it in the washing machine on my son's winter coat. He had a skunk in his trap. It worked great. I keep it on hand by the gallon. I also get that musty smell on fabric when I have things in storage. I am going to try "Simple Green" next time.
