Before first use place all components separately in boiling water for 5 minutes. This is to ensure hygiene. Sterilise using one of the following methods: steam sterilising (electric or microwave according to manufacturer’s instructions), boiling in water for at least 5 minutes or liquid sterilising solution. Do not use abrasive cleaning agents. Only soft bristle brushes or soft sponges should be used. Hard scourers may scratch the plastic.

Do not leave single bottle parts in direct sunlight or heat, or leave in sterilising solution for longer than recommended, as this may affect proper function. The bottle is made of polypropylene which is hygienic, easy to clean and relatively soft. Avoid heavy pressure on it, as this could affect the function.
