Silicone bakeware is favored by many home chefs because it provides a flexible and easy to use non-stick baking surface. Unfortunately, it can also absorb odors from strong smelling foods such as onion and garlic. To properly cleanse and deodorize your silicone bakeware, you should use mild household cleaning products that are also safe for human consumption.
Fill the kitchen sink with warm water, 1 tbsp. dish soap and 1/2 cup baking soda. The soapy water cleans and removes cooking residue, while the baking soda absorbs and removes odor.
Put the silicone bakeware into the soapy water and swish it around for about 10 seconds. Scrub it with a dishrag or brush.
Rinse the bakeware with warm water and allow it to air dry.
Sprinkle a thin layer of baking soda over the entire piece of silicone bakeware and let it sit for about 2 hours.
Rinse the bakeware in the sink with warm water and allow it to air dry.
