Reusable baby pouches are convenient, but they can be pretty tricky to clean, based on their shape, design, and size. First, you should rinse the inside part with lukewarm water and make sure to focus on the corners because food residue might get stuck there. The mouthpiece, as well as the zipper area, are also tricky elements that need more focus and attention on your part. Next, you can sanitize your pouches in hot water or, if the products you've purchased are dishwasher-safe, you can place them inside the dishwasher, on the top shelf, for an excellent sanitizing effect. Before washing the pouches, always open the zipper and take off the lids.
