Parts cleaning versus jewellery cleaning: why the same "ultrasonic cleaner" label covers very different tools
The term 'ultrasonic cleaner' spans two genuinely different product categories that just happen to share a cleaning mechanism. Jewellery and dental cleaners run lower power, smaller tanks and no heater, tuned for gentle, quick cycles on small, often delicate items. Parts cleaners like this 3L unit run significantly more power, a heater to cut through grease and oil, larger tanks to fit tools or components, and a degas mode to handle solutions and materials that trap air. Buying the wrong category for the job either wastes power and tank space on jewellery, or under-powers a genuinely dirty mechanical part — worth matching the tool to the task rather than assuming any ultrasonic cleaner does the same job.
