I have a almost new plastic click-clack container that I stored cinnamon in. these are hard clear plastic containers with the clamp down lids from KA. I've tried dish detergent & soaking with baking soda solution, but can't get rid of the cinnamon odor. It's in the lid and the container itself. It turned out to be too big for cinnamon so I wanted to use it for something else. Any other ideas on deodorizing a food container? It's not DW safe.
