Musty odor eliminator nature's way

I just read this; I don't know if it works but it is worth a try.

Debbie's Weekly Tip - musty smelling quilts? If you lay your musty smelling quilts outside on the grass for the day on a clean sheet and cover them with a sheet, something mysterious happens and the musty smell is gone when you take them inside. I'm sure there is some chemical reaction between the sun, the grass and the fresh air but who knows exactly what, I just know it works for me! I do it to my outdoor furniture cushions too, and skip the sheets, I just throw them in the grass for the day and it works - try it!
