The Mophorn Ultrasonic Cleaner works really well. I purchased this item to clean vintage bicycle components and it did an excellent job. The 15L unit accommodates cranksets without a problem and the little strainer that's included nicely holds the small parts. I filled the tank as recommended, added some citrus degreaser, set the temperature to 50 degrees C, and let it run for 20 - 30 minutes depending on how dirty the parts were. Most parts needed no additional cleaning. Some, like the teeth on the chainrings, needed a bit more work. Most parts, however, came out looking like new. I was doing this work in preparation for selling the parts, now they are so beautiful, I not sure I want to let them go.
