Abstract: Embodiments herein relate to the field of reusable storage bags, and, more specifically, to support systems for holding plastic bags of various dimensions open to facilitate washing in a dishwasher for later re-use. In various embodiments, the device may include first and second bag support members having a center shaft with a first end adapted to engage a prong of a dishwasher rack, and a second end adapted to retain a plastic bag in a desired position. In use, the first and second bag support members are placed over prongs having a desired spacing, and the bag is placed over the two support devices, where it is retained during the wash cycle of the dishwasher. The shape of the bag support members is adapted to retain the bag in an open position throughout the wash cycle, without allowing the plastic bag to tent or cause pooling.
