INVASION OF THE MOTH BALLS!

I bought a nice blazer from Goodwill recently (well more like a month or two ago) and it reeks of moth balls. I didn't notice it at the store but when I got it home the smell was really noticeable and even though I love the way the jacket looks and feels I hate how it smells. I tried to find remedies for the smell on the interwebbed internets but nothing so far is working. I don't have money for the dry cleaners so I was hoping you could help me find a solution that I may not have thought of. By the way I live in Bremerton Washington so anything involving the sun, heat, or fresh air would be out of the question.
