Why Does My Silicone Baking Mat Smell?

There could be a few reasons why your silicone baking mat is smelling. One possibility is that it has absorbed odors from the foods you have cooked on it. Another possibility is that it has not been cleaned properly and bacteria has built up on it. To eliminate the odor, you can try washing the mat with hot soapy water or placing it in the dishwasher. If the odor persists, you can try soaking the mat in a mixture of equal parts water and white vinegar for a few hours before washing it again.
