Ultrasonic cleaners generate microscopic cavitation bubbles that clean metal and hard gemstones effectively. They are ideal for solid gold, platinum, sterling silver, diamonds, rubies, and sapphires when settings are secure. Avoid using them on pearls, opals, emeralds (often treated), turquoise, costume or plated jewelry, and any item with loose or glued stones. Safe use includes inspection, a mild soap solution, a basket, short cycles, rinsing, and drying. When uncertain, consult a jeweler.

How ultrasonic cleaners work

Ultrasonic jewelry cleaners use high-frequency sound waves to create microscopic bubbles in a liquid. When those bubbles collapse (a process called cavitation), they dislodge dirt, grease, and grime from metal and hard gemstones without scrubbing.

What they clean well

Ultrasonic cleaners work best on solid metals (gold, platinum, sterling silver) and hard, durable gemstones such as diamonds, rubies, and sapphires when the stones and settings are secure. They remove oil, dust, and particles from small crevices that are hard to reach with a brush.

What to avoid

Do not use an ultrasonic cleaner on porous, soft, or treated stones. Pearls, opals, emeralds (often oiled), turquoise, lapis, coral, and amber can be damaged by the vibration or by cleaning solutions. Costume jewelry and pieces with glued-in stones or plated surfaces can lose their finish or have stones loosened. If any stone is loose, skip the ultrasonic cleaner and take the piece to a jeweler.

Safe cleaning steps

  1. Inspect each item for loose stones, cracked settings, or plating.
  1. Remove any pieces that are delicate, porous, or glued.
  1. Fill the tank with warm water and a drop of mild dish soap or a manufacturer-recommended solution. Avoid household bleach and harsh chemicals.
  1. Use a basket or rack to keep jewelry off the bottom of the tank.
  1. Run short cycles (30-90 seconds to start) and check the piece between cycles. Repeat only if needed.
  1. Rinse pieces well in clean water after cleaning and dry with a soft cloth. Inspect settings again.

Additional tips

  • When in doubt, ask your jeweler. Professional cleaning methods (steam, specialized solutions, or hand cleaning) may be safer for some pieces.
  • Avoid frequent ultrasonic cleaning for plated or older pieces - repeated cavitation can wear finishes over time.
  • If your jewelry was treated (fracture-filled, surface-coated, or oiled), confirm with the jeweler whether ultrasonic cleaning is safe.
Ultrasonic cleaners are efficient for many everyday pieces but carry risks for delicate or treated gems. A quick inspection and conservative use will let you get the benefits without damaging your jewelry.

FAQs about Ultra Sonic Jewelry Cleaner

Is it safe to clean diamonds in an ultrasonic cleaner?
Yes - diamonds themselves tolerate ultrasonic cleaning, and the method cleans settings well. Only use it if the stones are secure and avoid harsh chemicals. Run short cycles and inspect settings afterward.
Can I clean pearls or emeralds with an ultrasonic cleaner?
No. Pearls and many emeralds (often oiled) are porous or treated and can be damaged by the vibration and cleaning solutions. Use a soft cloth and mild soap instead, or have a jeweler clean them.
What cleaning solution should I use?
Use warm water with a drop of mild dish soap or a manufacturer-recommended solution. Avoid bleach and strong acids. Some jewelers use mild ammonia solutions for unwired gold and diamonds, but ammonia is not safe for porous or treated stones.
Will ultrasonic cleaners remove plating or damage costume jewelry?
Yes. Ultrasonic cavitation can strip plating and loosen glued-in stones used in costume jewelry. Avoid ultrasonic cleaning for plated or glued pieces.
How often should I use an ultrasonic cleaner on my jewelry?
Use it sparingly - periodic cleaning is fine for durable pieces, but frequent ultrasonic cleaning can stress settings and wear finishes. Inspect items regularly and clean professionally when in doubt.
