Sterilize before first use by submerging in boiling water for three minutes. After each subsequent use, we recommend that you rinse them with cold water, and then hand-wash them in warm, soapy water. If you choose to sterilize more often, non-heat methods are recommended. Do not sterilize in a steam sterilizer, sterilizing bag, or dishwasher.
