Many dishwasher bottle baskets use a combination of a lid and internal racks to secure small parts. Examples include a nipple-sanitizing lid, a patented straw-cleaning rack that holds straws upright, and an interior layout that keeps nipples, valves, and caps contained during washing.
Some listings note recycled content and renewable fibers (for example, items with 30% recycled cotton or labeled as containing recycled content or renewable resources). A craft certification cited on a few items is the Nest Seal of Ethical Handcraft.
