To clean solid copper, rub it with lemon juice and salt, rinse it, and dry it at once. Plated, sealed, and beaded pieces need dish soap or a dry cloth, and the table below shows how to tell which you have. Copper darkens with every touch and goes green in damp air, and it comes back to a rose-gold shine in under a minute with things you already have in the kitchen.
Why Copper Tarnishes
Copper tarnishes because it reacts with air, moisture, and skin. It does not rust and it is not ruined. Bright copper meets oxygen and forms a thin layer of copper oxide, first a warm brown and then nearly black. Add water, salt, or acid and the layer turns blue-green. All of it sits on the surface, and the metal underneath is unchanged.
Tarnish, Patina, and Verdigris
| Name | Color | What it is | What to do |
|---|---|---|---|
| Tarnish | Brown to black, dull | A thin film of copper oxide from air and handling | Polish it off, or leave it |
| Patina | Even brown, or an even green outdoors | Tarnish that has settled into a stable, protective layer | A matter of taste; many people prefer it |
| Verdigris | Blue-green, powdery or crusty | Copper salts formed by moisture, salt, sweat, or acid | Clean it off jewelry and tools; do not let it sit on skin or food surfaces |
The green of the Statue of Liberty is a patina about as thick as a sheet of paper, and it has protected the copper under it for well over a century.
Why Does Copper Turn Skin Green?
Copper turns skin green because sweat, lotion, and soap are slightly acidic and salty, and they dissolve a trace of the metal into green copper salts that stay on the skin. It is not an allergy and it is not harmful. It washes off with soap and water, it is heavier in hot weather and under a snug cuff, and a thin coat of clear nail polish or wax on the inside of the piece stops it.
Before You Clean: Know What You Have
How you clean a copper piece depends on whether it is solid, plated, sealed, or strung with something that cannot get wet. Check before you reach for the lemon.
| Piece | How to tell | How to clean it |
|---|---|---|
| Solid copper | The same color all the way through at edges and scratches; tarnishes evenly | Any method on this page |
| Copper plated | A thin copper skin over brass or steel; a different color shows at worn edges | Dish soap and a soft cloth only; acid and scrubbing strip the plating |
| Lacquered or sealed | Stays bright for months and never tarnishes; water beads on it | Dish soap and water only; polish removes the seal |
| Copper with stones or beads | Stones, glass beads, elastic cord, or tassels | Dry cloth on the metal; keep water and acid off stones and cord |
| Copper with magnets | Small magnets set inside the links or band | Damp cloth and a quick dry; do not soak |
| Two-tone or mixed metal | Copper with brass, silver tone, or steel | Dish soap, then a dry polishing cloth; acid can stain the second metal |
How to Clean Copper
Start with the mildest method that does the job. Dish soap lifts dirt and oil, lemon and salt lifts tarnish, a vinegar soak reaches into chain links and knotwork, and baking soda paste polishes. Every method ends the same way: rinse well, dry at once, and buff.
| Method | Best for | Time | Safe on plated or sealed pieces |
|---|---|---|---|
| Dish soap and warm water | Dirt, oil, fingerprints, weekly care | 2 minutes | Yes |
| Lemon and salt | Tarnish on solid copper | 1 minute | No |
| Vinegar and salt soak | Chains, braided cuffs, detailed solid pieces | 5 to 10 minutes | No |
| Baking soda paste | A final polish, light tarnish | 3 minutes | No |
| Ketchup | Tarnish on flat solid pieces when you have no lemon | 10 minutes | No |
Lemon and Salt: The One-Minute Method
- Gather. Half a lemon, one teaspoon of fine table salt, a soft cloth, and a dry towel.
- Mix. Squeeze the lemon into a small dish and stir in the salt, or dip the cut lemon straight into the salt.
- Rub. Rub the piece with the cloth or the lemon in small circles. The tarnish lifts in seconds, and a minute is enough.
- Rinse. Rinse under warm running water until the piece no longer feels gritty or slick.
- Dry at once. Pat it dry with the towel and then buff with a dry part of the cloth. Water left in the links is where tomorrow's green spots start.
- Protect. Rub on a thin coat of wax, or leave the piece bare and wipe it after each wear.
Use fine salt, not coarse. Coarse salt scratches.
Dish Soap and Warm Water
Will dish soap clean copper? It cleans dirt, skin oil, and lotion from copper, and it is the only cleaner that is safe on plated and sealed pieces. It does not remove tarnish. Put two drops of mild dish soap in a bowl of warm water, wash the piece with your fingers or a soft cloth, rinse, and dry at once.
Vinegar and Salt Soak
Stir one tablespoon of salt into one cup of white vinegar in a glass or plastic bowl. Lay the solid copper piece in it for five to ten minutes, no longer, then brush the crevices with a soft toothbrush, rinse very well, and dry at once. Do not soak pieces with stones, magnets, cord, or plating.
Baking Soda Paste
Mix three teaspoons of baking soda with one teaspoon of water, or with lemon juice for more bite. Rub the paste on with your fingers or a soft cloth, following the grain of the metal, then rinse and dry. It leaves a soft shine and is gentle enough for a last pass after lemon and salt.
How to Polish Copper to a Shine
After cleaning and drying, buff the piece with a jewelry polishing cloth or a clean piece of old cotton T-shirt, using long strokes in one direction. For a mirror finish on a plain cuff or a rod, a small dab of commercial copper cream, used as its label directs, does in one pass what lemon does in three.
What Not to Clean Copper With
- Bleach or chlorine. They pit copper and turn it black. Take copper off before the pool or the hot tub.
- Ammonia. It eats copper and leaves blue stains.
- Steel wool, scouring pads, or scouring powder. They scratch the surface, and scratches tarnish faster.
- The dishwasher. The heat and detergent dull and spot copper.
- Whitening toothpaste. It is an abrasive, and it strips plating.
- Long soaks. More than ten minutes in any acid starts to etch the metal and turns it salmon pink.
Never mix cleaners. Vinegar and bleach together, or ammonia and bleach together, release toxic gas.
How to Keep Copper From Tarnishing
You cannot stop copper from tarnishing, but you can slow it from days to months.
- Keep it dry. Take copper off before the shower, the dishes, the pool, the gym, and bed.
- Put it on last. Lotion, perfume, sunscreen, and hairspray first; copper after they dry.
- Wipe it after each wear. A soft dry cloth takes off the sweat and oil that do the damage.
- Store it sealed. A small zip bag with the air pressed out, or a lidded box, with a silica gel packet or an anti-tarnish strip. One piece per bag so they do not scratch each other.
- Wax it. Rub on a thin coat of microcrystalline wax, beeswax, or carnauba wax, let it haze for ten minutes, and buff. One coat lasts weeks on jewelry and months on a shelf piece.
- Seal the inside. Two thin coats of clear nail polish on the inside of a cuff or ring keep the green off your skin. Repaint when it wears through.
When to Keep the Patina
You do not have to polish copper at all. An even brown patina protects the metal, shows the detail in engraving and knotwork, and suits an altar better than a mirror shine for many practitioners. If you like the dark in the recesses and the bright on the high points, polish with a dry cloth only, which brightens what it touches and leaves the rest. Clean off verdigris, the crusty blue-green, wherever it touches skin.
Caring for Each Copper Piece
Copper Bracelets, Cuffs, and Rings
Solid copper cuffs such as the braided copper cuff and the snake copper cuff take the lemon and salt method; keep the lemon off the snake's set stones and clean around them with a cotton swab. Two-tone pieces such as the Om copper cuff and the copper and brass twisted bracelet get dish soap and a polishing cloth. To resize a cuff, squeeze or open it gently at the middle of the band, a little at a time; bending it at the ends or flexing it daily work-hardens the copper until it cracks.
Copper Bracelets With Stones and Beads
Beaded pieces are cleaned dry. On the copper and assorted stone bracelet and the Czech beaded copper bracelet, rub the copper beads with a polishing cloth and leave the stones alone. The selenite, quartz, and copper tassel bracelet must stay completely dry, because selenite dissolves in water. Water also weakens elastic cord, so none of these go in the shower.
Copper Magnetic Bracelets and Rings
Wipe magnetic pieces such as the heavy braided copper magnetic bracelet and the copper magnetic rings with a cloth dampened in soapy water, then dry them at once. Do not soak them; water trapped around a magnet rusts it. We sell copper and magnetic jewelry as jewelry and make no health claims for it. Anyone with a pacemaker or another implanted device should ask their doctor before wearing magnets.
Copper Dowsing Rods
Copper dowsing rods are handled more than any other copper tool, so they darken fastest on the handles. Both of our sets, the 12 inch and the 9 1/4 inch, have a copper sleeve handle that the rod turns inside. Wipe the rods with a dry cloth after every session. To brighten them, clean the long arms and the outside of the sleeves with lemon and salt or baking soda paste on a cloth, wipe with a wet cloth, not under the tap, and dry completely. Keep water, paste, and oil out of the sleeves; residue inside makes the rod drag. Store rods flat or hanging in their bag so the arms stay straight. Our dowsing rods guide covers how to use them.
Copper Pyramids and Altar Pieces
The copper pyramid frame and other shelf pieces tarnish slowly because nobody touches them. Dust with a dry cloth, clean once or twice a year with lemon and salt on a cloth, working one bar at a time, and finish with a coat of wax. Keep copper on the altar away from burning charcoal, salt bowls, and spilled moon water, all of which mark it.
Copper-Plated Pieces
Copper-plated crystal cages and plated pendulums have a copper skin thinner than a hair. Wash them in soapy water and dry them. Any acid, paste, or polishing cloth with grit in it will wear through to the metal beneath.
Copper in Spiritual Practice
Copper is the metal of Venus. The word itself comes from Cyprus, the island sacred to Aphrodite, where the ancient world mined it, and the old correspondences give it to love, beauty, harmony, and Friday. Practitioners keep copper for conducting: it carries heat and electricity better than any common metal but silver, and the lore extends that to energy, which is why wands, pyramids, and dowsing rods are made of it.
How to Cleanse Copper Spiritually
Washing takes off dirt; cleansing clears what the piece has picked up. For copper, use the dry methods:
- Smoke. Pass the piece through incense or herb smoke.
- Sound. Ring a bell or a singing bowl over it.
- Moonlight. Leave it on a dry windowsill overnight.
- Selenite. Rest it on a selenite plate overnight.
Skip the two cleansers that harm the metal. Salt, dry or wet, pits copper, and a soak in water or moon water speeds tarnish. Our guide to cleansing crystals explains each method in full.
Does Polishing Copper Remove Its Charge?
Polishing takes off a layer of oxide a few atoms thick, not the purpose you gave the piece. Many practitioners treat a polish as a fresh start all the same: clean the piece on a Friday, cleanse it with smoke, and hold it while you state again what it is for.
Where to Find Copper
Our copper pieces are gathered in the copper collection: cuffs and bracelets, magnetic rings, dowsing rods, the pyramid frame, and crystal cages. For more to wear, see all bracelets, and for the tools copper is made into, pendulums and divination tools.
Copper Care FAQ
How do you clean copper to make it shiny again?
Rub solid copper with the juice of half a lemon mixed with a teaspoon of fine salt for about a minute, rinse it under warm water, dry it at once, and buff it with a soft cloth. The tarnish lifts in seconds.
What is the best cleaner for copper jewelry?
For solid copper jewelry, lemon juice and fine salt, followed by a rinse and a thorough dry. For plated, sealed, or beaded copper jewelry, mild dish soap and a soft cloth, or a dry polishing cloth alone.
Will Dawn dish soap clean copper?
Dish soap removes dirt, skin oil, and lotion from copper, and it is safe on plated and sealed pieces. It does not remove tarnish; for that, solid copper needs a mild acid such as lemon juice or vinegar.
What should you not clean copper with?
Bleach, chlorine, ammonia, steel wool, scouring powder, whitening toothpaste, and the dishwasher. Do not soak copper in any acid for more than ten minutes, and never mix cleaners.
Does copper tarnish?
Yes. Copper reacts with air, moisture, and skin, turning brown, then nearly black, and blue-green where water or sweat sits on it. The tarnish is only on the surface and comes off with a mild acid.
Why does copper turn green?
Moisture, salt, and acid turn the surface of copper into blue-green copper salts called verdigris. Outdoors the same reaction slowly builds the even green patina seen on old roofs and statues.
Why does copper turn my skin green, and is it harmful?
Sweat and lotion dissolve a trace of copper into green copper salts that stay on the skin. It is harmless and washes off with soap. Clear nail polish or wax on the inside of the piece prevents it.
How do you keep copper from tarnishing?
Keep it dry, put it on after lotion and perfume, wipe it after each wear, store it in a sealed bag with a silica gel packet, and rub on a thin coat of wax every few weeks.
Can you wear copper jewelry in the shower?
It is better not to. Water and soap speed tarnish, leave green spots in links and settings, weaken elastic cord, and rust the magnets in magnetic pieces.
Should I remove the patina from copper?
Only if you prefer the shine. An even brown patina protects the metal and shows off engraved detail. Clean off crusty blue-green verdigris wherever the piece touches skin.
How do you clean copper dowsing rods?
Wipe them with a dry cloth after each use. To brighten them, clean the long arms with lemon and salt or baking soda paste, wipe with a wet cloth, and dry completely, keeping water out of sleeved handles.
Can you cleanse copper with salt or water?
Use smoke, sound, moonlight, or selenite instead. Salt pits copper, and soaking it in water or moon water speeds tarnish.
