Make sure you use very hot water. Lukewarm or cold water will not be quite as effective at cleaning your silicone bakeware.
While your preference might be to use a more natural dish soap, those ingredients won’t be nearly as effective for the tough stains you’ll find on your silicone bakeware.
You may have to spend quite a bit of time and energy getting rid of these stains.
Try to use even hotter water the second time. If you use rubber gloves, you’ll be able to use hotter water while cleaning your silicone bakeware.
Make sure you allow the silicone to dry completely before you begin using it again. This usually takes at least an hour or two.
After you’ve heated up the bakeware, try washing it with grease-cutting dish soap and baking soda. Be careful not to burn yourself while handling the bakeware when you remove it from the oven.
Be sure to give a generous sprinkling of the baking soda, not just a light dusting.
Let the baking soda dry completely, which could take several hours.
You may have to repeat this process quite a few times to get your silicone bakeware perfectly cleaned.
Be sure not to store your silicone bakeware in the cabinet while it is still wet, as this could lead to mold and bacteria forming on your kitchenware.
At the very least, fill the silicone bakeware with water and dish soap immediately after use so you can go back and clean it later.
Using an abrasive sponge can chip off pieces of the silicone and, over time, minimize the nonstick elements of the pan.
Additionally, using cooking sprays with silicone bakeware will contribute to the sticky, greasy mess you have to clean up later and cause more damage to your pan over time.
