Silicone in itself is odourless, but smells from food, oils, plastics or detergent can take a liking to your We Might Be Tiny products. If possible store your We Might Be Tiny dinner and bakeware separately to plastic products because they can absorb a plastic smell if kept in close proximity for too long.
If your product has taken on a scent of something it has come in contact with, placing it in boiling water for about 15 minutes or baking it in the oven at 100°C (212°F) for about an hour should remove any smell.
