Abstract: A compartmented, basket-like accessory for washing nipple and cap components of infant-feeding bottles in a conventional automatic dishwashing machine. The accessory can be mounted easily and quickly in the article rack found in most conventional automatic dishwashing machines. The top section and bottom section of the accessory preferably are made of perforated plastic to permit the water to pass through freely during the washing and rinsing cycle. A plurality of smaller nipple compartments are each provided with a vertical, prong-like, nipple positioner, centered to hold the nipples upright during the washing and rinsing cycle. Similarly, a plurality of larger cap and ring compartments are each provided with a vertical, prong-like, cap and ring positioner, centered to hold the caps and rings in a fixed position during the washing and rinsing cycle.
