How do I clean and sterilise the RapidCool™ lid?
The digital lid should be cleaned in warm, soapy water. After cleaning, the lid should be sterilised by UV sterilisation or cold-water sterilisation. You can also sterilise the RapidCool™ digital lid when out and about using hot water from your insulated flask. The RapidCool™ lid must glow Nuby red when attached to the flask to indicate the water is at the correct temperature. Keep the flask upside down to make sure the water is in contact with the lid for at least 30 seconds, then the lid will be safe to use!
You can do this via UV sterilisation, cold water sterilisation, steam sterilisation or in a dishwasher. Never steam sterilise in a microwave.
The insulated flask will keep water above a safe temperature to make a feed for at least two hours, when pre-heated with boiling water first. The insulated flask works with the digital lid to show you with a red ‘Nuby’ that the water is still hot enough to kill any bacteria in your little one’s formula.
No, you don’t have to wait! The freshly boiled water can and should be used immediately for the safest feed. The NHS guidelines state that the water should be no less than 70°C, but this does not mean that you must wait for it to reach this temperature first before mixing with formula. Mixing formula with freshly boiled water is the safest way to feed, as it ensures any harmful bacteria are eliminated!
The RapidCool™ works by absorbing heat from hot liquids. After being exposed to heat, it will require a minimum of 3 hours before being ready to use again. The flask should feel cool to the touch.
