Silicone bakeware is versatile and user-friendly. It’s naturally nonstick and easy to pop things out of, it’s made of inert material, and it’s easy to store (pieces can often be collapsed down to save space). We love silicone bakeware for making heart-shaped Valentine’s Day cakes, freezing ounce-sized portions of baby food, baking up banana bread, and more.

But our love for silicone comes to a screeching halt when the giant ice cubes we made for cocktails taste suspiciously like last month’s pesto bombs. Not ideal. Another problem people encounter with new silicone bakeware is that they sometimes imbue food with a “plasticky” taste and smell when they’re brand new. And soaking your silicone pieces in soapy water can leave them smelling like soap or imparting a soapy flavor onto your food.

If you’ve ever tried and failed to rid your silicone bakeware of odors and tastes, you know how frustrating and futile it can feel. Short of keeping one set for sweet stuff and one set for savory recipes, there’s one more thing you can do. See, we have this great method that’s super easy and incredibly effective. Keep reading to get the steps.

Preheat your oven: Preheat your oven to 350 degrees.

How To Get Lingering Smells Out of Silicone Bakeware

What You Need

  • An oven
  • A sponge and dish soap
  • A baking sheet
  • Oven mitts


  1. Preheat your oven: Preheat your oven to 350 degrees. 
  2. Wash your silicone bakeware: Give your bakeware a quick wash (with a sponge and warm, soapy water) to ensure there isn’t any lingering oil or bits of food left on your bakeware. You don’t want it to bake on in the oven. 
  3. “Bake” your bakeware: Put the pieces on a baking sheet (this will make things easier to get in and out of the oven) and bake your bakeware for one hour.
  4. Try the sniff test and let the pieces cool: Pull the baking sheet out of the oven and perform a careful sniff test. If you’re getting even the faintest stinky whiff, return the sheet to the oven in increments of 20 minutes. Once they’re stink-free, let the pieces cool before you put them away.


  • Make sure your cookware is 100 percent silicone. Look for labeling to ensure your cookware is made completely of silicone. Rubber could melt and fillers in your silicone could also pose a melting problem.
