Ultrasonic Jewelry Cleaning Machine

A bench-top ultrasonic cleaner that lifts dirt, polishing rouge, oil and oxidation out of rings, chains, watches and optical parts — 40 kHz cavitation in a heated stainless-steel tank, with no abrasive scrubbing.

Product Overview

What the ultrasonic cleaner does

The ultrasonic jewelry cleaning machine cleans by cavitation. A generator drives a transducer bonded to the base of a stainless-steel tank, sending 40 kHz sound waves through the water-based bath. Those waves form millions of microscopic bubbles that implode against the surface of the work — lifting dirt, oils, polishing rouge and oxidation out of settings, links and engraving that a brush simply cannot reach.

Because the action is physical, it needs only water with a few drops of mild detergent. There is no abrasive tumbling, no aggressive acid and no risk of rounding off fine detail. Heated models add a thermostat, so the bath can be held at the temperature that best releases wax and grease.

Units are offered from a single bench-top tank for a repair bench up to larger baskets for batch cleaning, so the same process covers a one-off ring and a full tray of findings.

How it works

Simple to run, repeatable on every batch

No operator skill is required — fill, load and set the timer. Because the cycle is timed, the same setting gives the same result every time.

1 · Fill

Fill the tank with water to the marked level and add a few drops of mild detergent.

2 · Load

Place the pieces in the stainless basket so they never touch the tank floor.

3 · Set

Set the cleaning time on the timer; on heated models set the thermostat first.

4 · Lift out

Remove the basket, rinse and dry — then repeat on the next batch with the same setting.

What it cleans

Parts that come out bright again

  • Rings, chains & bracelets

    Clears polishing compound and everyday grime from settings and links without disturbing stones that are safe for immersion.

  • Watches & metal straps

    Lifts soil from bracelet links and case crevices; stainless straps and cases come up clean around the clasp and lugs.

  • Eyeglasses & optical frames

    Removes skin oil and dust from nose pads, hinges and the base of lenses — a standard step in any optical workshop.

  • Coins, medals & metal findings

    Loosens surface dirt and oxidation from collectible and batch metal parts while leaving sound metal and its patina intact.

  • Dental & laboratory instruments

    A repeatable pre-clean for small stainless instruments and tools before sterilisation.

  • Precision hardware & small parts

    Screw-machine parts, fasteners and small assemblies are degreased in bulk without hand-scrubbing.

FAQ

Questions buyers ask before ordering

Which size should I buy?

Pick the tank by the largest item you clean; we offer bench sizes for rings up to larger baskets for batches.

Do I need heating?

Heating helps loosen wax and oils, so a heated tank is recommended for jewellery and optical parts.

What liquid do I use?

Use plain water with a few drops of mild detergent; avoid solvents that attack the tank.

What should NOT go in?

Avoid porous gems, soft stones and items not rated for immersion. Ask us if you are unsure.

Cleaning a specific part or batch?

Send us the item, the material and the quantity you clean per day — an engineer replies within one working day and can run a free cleaning test on your sample.
