I'm always getting fabric from family or friends that has that musty smell. If they are big pieces I do wash them, but the smell is still there. Last night I went to use some of those pieces I had and thought as I was ironing, I would spray with my Febreeze and then iron. Worked like a charm. It seemed to set that good smell in. Try it on your smaller pieces and see if it works for you. Worth a try.
