My wife is vegetarian and she often complains about the ice in the freezer smelling and tasting of meat or fish. If you want ice to be fresh, Real Simple suggests de-stinking your freezer with some baking soda first.
Baking soda is a good way to deodorize anything from stuffed animals to stinky shoes, and using it in the freezer is hardly a new tip. But you might not have thought to use it in this particular context. Real Simple advises first cleaning the freezer entirely with baking soda, which has an abrasive quality that scrapes away dirt and gunk, and also absorbs odors. Next, punch a few holes in a fresh pack of baking soda and just leave it in the freezer. It will continue the odor absorption to prevent your freezer from stinking.
