Washing baby bottles with soapy water alone doesn't always remove ground in milk protein, pulp & juice residues, which can cause baby stomach upsets. In response to this problem NUK has developed the Baby Bottle Cleanser specifically for cleaning all types of baby bottles, soothers & accessories. It is based on natural ingredients & contains specific enzymes which effectively remove milk protein, pulp & juice residues. Its mild formula makes it 'baby safe'. Simply add a measure of the NUK Baby Bottle Cleanser to a little warm water, & wash your baby's bottles, teats & accessories thoroughly, then simply rinse away. The NUK Baby Bottle Cleanser is more effective at removing milk protein, pulp & juice residues than soapy water alone but doesn't replace sterilizing baby bottles. BPA (Bisphenol A) free. Perfect for cleaning baby bottles & teats. Rinses fast & easily. Based on natural ingredients. p H-skin-neutral (dermatologically tested). Free of perfumes & dyes.
