I ended up returning this product. I really love the Dapple baby soap for washing bottles and when I found this I was so excited because my LO is old enough where I don’t have to kill myself to wash and boil everything. Using the dishwasher saves me 2 hours of trouble washing bottles and pump parts every other day. This product leaves milk residue inside the bottles and I have to rerun my dishwasher with the Seventhgeneration free and clear packs. I highly recommend seventh generation, milk residue is no match and everything is clean and doesn’t need rewashing.
