Cleans effectively and is completely safe for your child. After washing up, everything is clean and there are no traces of bottle cleanser. The NUK Bottle Cleanser will win you over with no fragrance. With no colorants. But with a whole lot of ”performance“. PH-neutral and hypoallergenic. Because we rely on the strength of nature. With enzymes that are particularly effective at dissolving milk, juice, and, thanks to the new formula, even puree residue.
