The performance and integrity of silicone utensils are highly dependent on how they’re stored. The best way to ensure longevity of this material is to keep it stored in a dry and cool place away from sunlight. Use drawer organizers or utensil holders to prevent sticking and scratching. Do not stack utensils heavily as that can warp their shapes too. If stored correctly and with care, silicone utensils can be used for a long long time which makes them great for cooking.
