The NUK Nasal Decongester hygienically clears mucus from around baby's blocked, stuffy nose with ease. When babies catch a cold, they're not able to blow their nose because they have yet to learn that important skill! Fear not though, help is at hand; the Nasal Decongester from NUK is here to ensure that your child doesn't suffer with a snotty, blocked nose! The NUK Nasal Decongester gently cleans baby's blocked nose, simply hold the nozzle up to one nostril, press the other nostril gently with your fingertip, squeeze the pump ball and gently reduce pressure, this will extract mucus from your baby's nose leaving them with a clear, snot free nose! To clean, separate the soft PVC pump ball and PP nozzle and clean thoroughly after each use with either hot soapy water or the NUK Baby Bottle Cleanser. Do not sterilise in a Microwave or Steam Steriliser as there is a risk that the Decongester could explode.
