Another option from someone who is so allergic to things that I can't use any type household cleaner and can usually only wear 100% cotton. I can't use any type product that out-gases and believe me that is a looonnnng list. Just ask my allergist!!
Take a pair of panty house (does anyone still have any of those? LOL). Cut about a 3 inch piece across. Tie one end. Put in about 2 tablespoons of baking soda. Tie the other end. Voila!! Takes away smells but doesn't leave any!! I change out about every 3 months. I keep these in all my clothes drawers, closets, and any plastic containers I use. I even put them under the sinks to keep away that musty smell.
