The Ultrasonic Jewellery Guide
Ultrasonic, hand cleaning or a jeweller?
By SONIQ LABS · Updated 8 November 2026
The right method depends on the piece and the problem. A machine, a gentle hand clean and a professional inspection serve different purposes.
Compare the job, not just the equipment
| Method | When it can make sense | Limits to consider |
|---|---|---|
| Gentle hand cleaning | A suitable piece with accessible everyday dirt; a simple routine you can control. | The liquid and brush must suit the item. Do not force a brush into delicate settings. |
| Home ultrasonic cleaner | Jewellery confirmed suitable for the process, especially with accessible details that are awkward to brush. | Not suitable for every stone, treatment or finish. Does not replace setting checks. |
| Professional jewellery service | Unknown materials, persistent dullness, damage, loose stones or a piece needing assessment. | Service scope and charges vary. Ask whether cleaning and inspection are included. |
First identify the problem
- Everyday dirt and oils: choose a cleaning method allowed for the piece.
- A darkened silver surface: ask whether it is tarnish or an intentional finish before treating it.
- Scratches: cleaning does not remove physical surface damage; ask about suitable professional finishing.
- A loose or damaged setting: arrange an inspection before cleaning.
- A stone that stays cloudy: have it examined rather than escalating the cleaning process.
If a hand clean is enough, keep it simple
There is no need to buy a device to solve a problem you have already solved. Follow the jewellery maker’s approved method and avoid abrasive household substitutes.
When a machine earns its place
Consider one when you have suitable jewellery to clean regularly and value reducing the brushing involved. Check tank fit, operating instructions and care requirements. An attractive machine that does not suit your pieces is still the wrong purchase.
Our buying checklist helps you compare those details without relying on claimed awards or unexplained ratings.
Keep inspection separate from cleaning
A sparkling ring is not proof that its settings are secure. Ask your jeweller about an inspection schedule appropriate to the item and how you wear it.
