Aluminum chopsticks are really easy to clean... by hand.In the dishwasher, they are too narrow for the holes in the removable cutlery basket and too light to withstand the blasts of water from below. After too many washes where I'd have to collect the chopsticks from the floor of the dishwasher, I decided it was time to make a change.
Zip-ties on the top rack provide a harness of sorts for the chopsticks. The chopsticks are held in place tightly enough to prevent being knocked off the top rack. Not only that, but they slide under very easily, and I can fit up to six chopsticks in there at once. They ties are out of the way, don't interfere with other dishes, and are barely noticeable on the wire rack.
Three zip-ties. Two minutes. Chopsticks under control.
