I Learned That Baking Soda Helps With Mildew. I Sprinkled

I learned that baking soda helps with mildew. I sprinkled about two boxes underneath my bed where the odor came from. over time that has been this loud keen order that like a big plastic bags that I brought at the dollar store. Like a chemical that some plastic items release. Do you think it could be coming from the baking soda that I put down.
