Most of the jewelry that arrives on our bench damaged by cleaning was not damaged by dirt. It was damaged by the cleaner — toothpaste on a polished band, a silver dip poured over a pearl, a supermarket ultrasonic run on a ring whose stone was already moving. The good news is that the safe method is the cheap one: warm water, a drop of dish soap, a soft brush and five minutes.
The five-minute method
This is safe for solid gold, platinum and hard stones — diamond, sapphire, ruby. If your piece has pearls, opals, emeralds, turquoise, coral or amber, skip to what each material can take first, because those need wiping, not washing.
- Check the stones before you startTap the stone with a fingernail next to your ear, then try to rock it with a fingertip. If anything ticks, rattles or shifts, stop and put the piece away. Water, brushing and handling are exactly what finish off a setting that is already failing. The full test is in our guide to the six signs a stone is working loose.
- Work over a bowl, not an open drainWarm water — not hot — one drop of mild dish soap, and the sink plug closed. Most stones lost at home go down a drain during cleaning, not while the piece is being worn.
- Soak only what can take itTen to fifteen minutes is plenty for solid metal and hard stones. Anything soft, porous, glued, plated or costume does not get soaked at all.
- Brush gently, mostly from underneathA soft toothbrush and light pressure. Spend most of the time on the back of the setting, where hand cream, soap and skin oils collect — that film under the stone is what makes a diamond look tired, not anything on top of it.
- Rinse, dry fully, then storeRinse in clean warm water over the bowl, blot with a soft lint-free cloth and let the piece air-dry completely. Water trapped under a setting leaves a cloudy film and, on silver, speeds up tarnish. Store pieces apart from each other so harder stones do not scratch softer metal.
Rings come off before the pool, the gym and the cleaning cupboard. Chlorine attacks the alloys in gold over time and can weaken the very solder joints and prong tips that hold your stones. It is slow, invisible damage — and it is the reason plenty of prongs fail years earlier than they should.
The six things to never use
Every one of these is a repair we have had to quote after someone tried to save a cleaning bill.
1. Toothpaste and baking soda. Both are abrasives. They brighten metal by sanding it, leaving a haze of fine scratches, rounding off crisp edges and engraving, and thinning plated finishes. Polishing is not reversible.
2. Bleach and chlorine, in any concentration. They attack the alloys in gold and can cause it to crack. There is no safe household dilution.
3. Silver dips on anything set. A dip removes tarnish chemically along with the darkened detail in engraving, and it can permanently dull pearls, opals, turquoise and coral. On an antique piece it also strips the patina that gives the piece its age and value.
4. Ammonia on treated or porous stones. Fine on a plain diamond solitaire, wrong on emeralds, opals, pearls, turquoise and anything oiled, dyed or fracture-filled.
5. Boiling water and sudden temperature changes. Thermal shock can crack emeralds and opals and can loosen stones set in glue rather than metal.
6. A home ultrasonic cleaner on anything set with stones. Ultrasonic vibration shakes a stone that is already loose right out of its setting. It is the single fastest way to turn a $79 setting job into a lost stone.
What each material can actually take
The rule underneath this table is simple: hard and solid can be washed, soft and porous can only be wiped.
| Piece | Safe at home | Never |
|---|---|---|
| Gold or platinum, no stones | Soak, soft brush, rinse, dry | Abrasives, bleach |
| Diamond, sapphire, ruby | Soak, brush the back of the setting | Home ultrasonic if any stone moves |
| Emerald | Damp cloth, dry immediately | Soaking, ultrasonic, heat, ammonia |
| Pearl, coral, amber, turquoise | Wipe with a barely damp soft cloth | Soaking, ultrasonic, dips, perfume |
| Opal | Wipe only, keep it away from heat | Soaking, ultrasonic, thermal shock |
| Silver | Soapy water, then a dry polishing cloth | Dips on set or antique pieces |
| Plated or costume | Dry wipe only | Soaking — it lifts glue and plating |
Pearls go on last, after perfume and hairspray, and come off first. Silk thread absorbs oils and stretches with wear, which is why strands eventually need restringing rather than cleaning.
When dull is not dirt
Three things get mistaken for a piece that needs cleaning. None of them get better with soap, and one of them is urgent.
White gold that has gone slightly warm or yellow
That is not dirt and it is not damage. White gold is finished with rhodium, a bright white plating that wears off with time and lets the natural tone of the gold show through. Cleaning does nothing; re-plating restores it. For a ring worn every day it is worth doing roughly every one to two years.
A film under the stone that will not wash out
If dirt keeps coming back in the same spot no matter how carefully you brush it, the dirt is being held there by a gap that should not exist. That is a setting question, not a cleaning question — check for movement using the 60-second test before you wear the piece again.
Fine scratches all over the surface
Scratches are metal that has been moved, not soil that can be lifted. They come out on the bench with proper polishing and refinishing, which is deliberately different from the abrasive shortcuts above: done correctly it removes the least metal it can, because over-polishing thins metal and rounds off detail that cannot be put back.
What the bench does that a sink cannot
Professional cleaning is not stronger soap. It is a different set of tools, used after somebody has looked at the piece:
- Ultrasonic cleaning that reaches behind settings and under stones — run only once the setting has been inspected, which is the part a home machine skips.
- Deep steam cleaning that lifts what is left, on all metals.
- Hand polishing and refinishing to bring back the original luster, matched to how the piece was made — matte, brushed or high polish.
- Rhodium re-plating for white gold, restoring the bright white finish and adding protection.
- Trained gemologists (HRD Antwerp and the ERIJ Foundation) on hand for anything set with stones, so delicate and treated gemstones are protected throughout.
| What you want done | Where it happens | Starting at |
|---|---|---|
| Routine cleaning between wears | Your kitchen, five minutes, warm soapy water | Free |
| Ultrasonic, steam, hand polish, rhodium | Polish & cleaning on our bench | $35 |
| Cleaning as part of any repair | Included with the repair, never sold as an add-on | Included free |
These are the lowest starting points, not the final price. Every piece is inspected and quoted individually — you get one firm number, and nothing is worked on until you approve it.

A trained jeweler replies within one business day with an honest answer — and if it does need the bench, the shipping kit and insurance both ways are free, and you pay nothing until you approve the quote.
Frequently asked questions
What is the safest way to clean jewelry at home?
Warm water, one drop of mild dish soap, a soft toothbrush and a bowl. Check first that no stone moves, work over the closed drain, brush mostly the back of the setting, rinse and dry completely. That method is safe for solid gold, platinum and hard stones such as diamond, sapphire and ruby, and it is the only method most pieces ever need between professional cleans.
Can I use toothpaste or baking soda to clean jewelry?
No. Both are abrasives. They do make metal look brighter for a day because they are sanding the surface, and that is the problem: they leave a haze of fine scratches, round off crisp edges and engraving, and thin plated finishes. What looks like cleaning is slow polishing, and polishing is not reversible.
Can I clean pearls, opals or emeralds at home?
Only by wiping them. Pearls, opals, turquoise, coral and amber are soft or porous, and most emeralds are oiled, so soaking, ultrasonic cleaners and chemical dips can dull them permanently. Wipe with a barely damp soft cloth, dry them, and put pearls on last after perfume and hairspray and take them off first.
Is an ultrasonic cleaner safe to use at home?
It is the tool that does the most damage in the wrong hands. Ultrasonic vibration shakes a stone that is already loose right out of its setting, and it can crack or dull emeralds, opals, pearls and treated stones. On our bench a piece is inspected first and cleaned ultrasonically only once the setting has been checked. If you own one at home, use it on plain gold chains and nothing set with stones.
Why is my white gold ring still dull after cleaning?
Because that is usually not dirt. White gold is finished with rhodium, a bright white plating that wears off over time and lets the natural warmer tone of the gold show through. No amount of cleaning brings it back, but re-plating does. For a ring worn daily it is worth doing roughly every one to two years.
How much does a professional cleaning cost?
Polish and cleaning work starts at $35 and covers ultrasonic cleaning, hand polishing, rhodium re-plating and deep steam cleaning. If your piece is coming to us for a repair anyway, ultrasonic cleaning and polishing is already included free with every repair and is never sold as an add-on. Every piece is inspected and quoted individually, you get one firm number, and nothing is worked on until you approve it.
