This workflow describes controlled ultrasonic cleaning with LUXI iClean concentrate after polishing has been fully completed. LUXI iClean removes polishing-compound residue, removed-metal particles, oily film, and other contamination. It does not correct scratches, haze, incomplete polishing, geometry errors, or surface defects.

Assess the whole item first

Use ultrasonic cleaning only when the whole item permits it, not merely the base metal.

Before immersion, assess:

  • base material;
  • stones and pearls;
  • enamels;
  • adhesive joints;
  • decorative, protective, electroplated, and PVD coatings;
  • hollow elements;
  • settings;
  • soldered joints, connections, and complex construction.

The confirmed base-metal scope includes gold, silver, brass, bronze, platinum, palladium alloys, and stainless steel. Sensitive elements may still require a gentler approved cleaning method or exclude ultrasonic cleaning completely.

Do not begin an ultrasonic cycle when whole-item compatibility has not been established.

Before immersion

Polishing must be complete. Do not use LUXI iClean instead of further polishing or preparation correction.

Remove accessible visible compound residue by a suitable safe method. Inspect the surface, relief, settings, inside angles, undercuts, and spaces between elements. Identify zones where compound is packed particularly tightly.

Working solution

Prepare one part LUXI iClean concentrate with ten parts water.

The working-solution temperature must not exceed 50 °C. Higher temperature is not a remedy for excess compound, a contaminated polishing tool, or residue packed into deep relief.

Use a clean tank and solution that has not been contaminated by previous processes.

Normal cycle

The normal ultrasonic cycle is approximately 30 seconds.

Then:

  1. stop the cycle;
  2. remove the item;
  3. inspect the surface and difficult-access zones;
  4. check stones, enamel, coatings, adhesive joints, and other sensitive elements.

One cycle must not exceed 60 seconds. Perform a repeat cycle only after inspection confirms that the item and its sensitive elements remain stable.

Do not automatically increase temperature, ultrasonic power, or cycle duration when contamination remains.

If compound remains

First identify the cause:

  • whether too much polishing compound was applied;
  • whether the wheel or other tool was contaminated with removed metal;
  • whether the contaminated zone is accessible to solution and ultrasonic action;
  • whether compound is packed deeply into relief, an undercut, or a space between elements;
  • whether the selected cleaning method matches the item construction.

Excess compound and poor access cannot be safely compensated by higher temperature, power, or cleaning duration.

Completion criterion

Cleaning is complete when:

  • no polishing compound, removed-metal particles, oily film, or contamination remains on open surfaces;
  • no visible residue remains in settings, inside angles, undercuts, relief, or other difficult-access zones;
  • the surface retains its lustre, colour, and original condition;
  • sensitive elements remain unchanged.

Before plating, PVD, or another coating operation, inspect the clean surface under directed light.

Rinsing, steam, and drying

After ultrasonic cleaning, rinse the item thoroughly in clean water, steam-clean it, and dry it completely after confirming that the whole item permits these operations.

No working-solution residue, loose contamination, or dried water spots may remain.

Perform final assessment only after complete rinsing, drying, and cooling.

Stop conditions

Stop cleaning immediately if:

  • the surface becomes hazy;
  • lustre decreases;
  • the colour of metal or coating changes;
  • a coating begins to change;
  • a stone, pearl, or enamel changes;
  • an adhesive joint becomes unstable;
  • a hollow element or joint releases signs of unstable contamination;
  • any sensitive element shows a change.

Do not perform a repeat cycle until the cause has been identified and whole-item suitability for ultrasonic cleaning has been reassessed.
