Here's the "Solution"
I had a brand new bedspread, that picked up a musty smell from an RV we had used. I tried everything, to get the odor out. Of course I could not use bleach on this fabric. A musty odor is almost impossible to get rid of, once an item has been exposed, no matter how clean you get it! Ahhh, at last, I remembered that I still had some "Simple Solution Stain and Odor Remover" on hand. You can buy it at most pet stores. It's the best thing I have ever found, for removing the smell left in the carpet from our aging, incontinent kitty. It has never damaged my carpets, so I thought, why not?!

Stored clothing can develop a musty odor over time. Hanging it near an open window can help air it out and potentially cause the odor to dissipate. This is a page about removing musty smell from a wedding dress.
