Before you start
- Identify the metal and check for plating, gilding or an intended patina first.
- Wipe light tarnish with cotton dampened with denatured alcohol.
- Dry the piece completely before you put it away.
Tarnish on silver is a dark layer of silver sulfide that forms when sulfur in the air reacts with the metal. Copper, brass and steel dull or brown in their own ways, and on some pieces that color is a patina you may want to keep, since polishing destroys it. Every cleaning takes a little metal with it, so it pays to start gently and act while the tarnish is still light.
Brass that's only lightly tarnished lifts with a gentle wipe, so test a hidden spot first. Very tarnished brass usually needs several gentle rounds, and you should stop if the surface starts to look rough. Tarnished silver jewelry and chains are easier to handle, but an antique brown finish you want to keep is a job for a pro.

5 steps
Step by step
Step 1 of 5
Identify the metal first
Check what the metal is and whether it has plating, gilding or a patina you want to keep. Look at the surface in good light, since a brown, gray or black layer may be intentional.
Step 2 of 5
Wash off dirt with soap and water
Wash the piece with a sponge and a mild soap-and-water solution to lift off dirt and grime before any tarnish work. Rinse thoroughly so no soap is left behind.
Tip. Wheels and bumpers collect road salt, so rinse those especially well.
Careful. Never apply cleaners to hot chrome or wheels; let the metal cool first.
Step 3 of 5
Wipe light tarnish with alcohol
Once the piece is dry, dampen cotton with denatured alcohol and wipe the tarnished area gently. Change to clean cotton as it darkens, and keep going until the cotton stops picking up residue.
Tip. Light tarnish sometimes wipes off on the first few passes, so try this before anything stronger.
Step 4 of 5
Dry completely and protect
Dry the piece completely with a soft cloth. Then protect it: oil or a rust inhibitor on clean, dry bare steel tools, and a wax or chrome preservative on bright metal.
Step 5 of 5
Clear rust from bare steel
For light rust, rub with 000 or 0000 steel wool or a wire brush. For severe rust, soak the tools overnight in white vinegar, then wipe with a damp rag, dry, and brush or steel-wool off what is left.
Careful. Don't leave tools in vinegar or store them wet; leftover moisture causes rust.

Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
See what to do for what you're seeing →Heavy buildup usually takes more than one round.
Heavy or long-standing buildup →When to call a professional →How to tell it's working
On silver, the cotton picks up dark residue at first and then stays clean once the light tarnish is gone. Stop there rather than rubbing harder. If the tarnish still looks dark after the alcohol wipe, the set-in options are the next step, and they are stronger and need more patience.
What changes for yours
Adjust for your metal, chrome & tools
Copper
Copper often carries a brown or green patina that many people want to keep, so check for one before you clean. If the layer is ordinary tarnish instead, the same soap-and-water wash and alcohol wipe apply.
Stop once the cotton stops picking up residue, because more rubbing only takes more metal off.
Brass
Brass gets the same light tarnish as other bright metals, so the alcohol wipe is the first thing to try after the wash. Check for a coating first, since that changes how the piece should be treated.
If the brass still looks dull after wiping, stop there and move to the set-in options for heavier tarnish.
Silver jewelry and chains
Jewelry and chains are often hollow, plated or set with stones, so check each piece before you wet it. Only wash a piece that is solid metal, and keep the stones and any wood or ivory parts away from liquid.
For the rest, work on one small area at a time with fresh cotton so the residue doesn't spread back across the piece.
Heavily tarnished brass and copper
Heavy tarnish on brass or copper is harder to shift, and stronger methods take more metal with them. Start with the alcohol wipe and repeat it with fresh cotton before going further.
If the color still won't lift, use the set-in method and go slowly, since each round removes a little more of the surface. Stop once the piece looks even.
Silver plate and plated items
Plated items have a thin coating, so every bit of polishing can wear through it. Use only the alcohol wipe on plated pieces and avoid anything abrasive.
Keep the cotton light and the rubbing short, and stop as soon as the tarnish is gone. If a plated piece is already worn, do less rather than more.
Other metals
For metal you can't identify, start with the wash and the alcohol wipe, then check the surface before going further. If you can't tell what it is, don't go past the alcohol wipe.
Once the piece is clean, dry it fully before you store it, and protect it with the finish that suits the metal.
Aluminum and steel
On aluminum, skip the vinegar, wire brushes and abrasive cleaners, since acid and abrasive cleaners are not safe there. Soap and water is the safe choice.
Bare steel can take the overnight vinegar soak and steel wool for rust. Chrome-plated and anodized parts are different, and they can't take steel wool or strong alkaline detergents.
Severely tarnished silver
Severe tarnish on silver is the job for the set-in method below, which is stronger and needs more patience. Use fresh cotton for each pass, since old cotton carries the tarnish back onto the silver.
Stop once the surface looks even, because more rubbing only takes more metal. If it still looks dark after a couple of rounds, stop rather than push harder.
Old coins and knives
There's no safe cleaning method here for old coins, and very old metal may have a patina that's worth keeping. Polish, abrasives and dips are the wrong tools for both.
For an old knife, the rust steps apply to bare steel only, so check the blade for a finish first. If you're unsure about a coin or antique, leave it as it is and have it looked at before cleaning.
Heavy or long-standing buildup
Old, heavy tarnish won't lift with a single alcohol wipe. It calls for the set-in method, which means polishing with precipitated calcium carbonate in denatured alcohol on cotton and changing the cotton often.
If the discoloration is dried on or sits in the recesses, use the set-in method only on that spot and as little as possible. For chemical dips, apply them locally, leave them on only as long as needed to avoid pitting, and rinse thoroughly.
Realistically, set-in tarnish may not come off completely, and some dark color can remain in the detail of an intricate piece. Stop after two rounds instead of pushing harder, because each round takes a little metal with it.

What makes it worse
Mistakes to avoid
Don't polish off a patina or gilding
A patina is a thin, fairly stable layer, often brown, gray or black, and polishing destroys it. Gilding is lost the same way, and removing tarnish always takes some metal with it, so check before you start.
Don't reach for general polishes
General metal polishes and harsh abrasives remove more metal than the tarnish does. Commercial polishes with ammonia are a poor choice for valued pieces, and multi-purpose metal polishes are not for silver at all.
Don't use bleach on silver
Bleach is not safe on non-stainless steel, aluminum or silver, and it must never be mixed with vinegar, ammonia or any other cleaner. Chlorine-processed gloves can also tarnish silver, so handle the pieces with clean cotton instead.
Don't soak hollow or composite pieces
Water gets trapped in hollow handles and in composite pieces with wood or ivory parts, and it can damage them. Keep these pieces out of water and chemical dips altogether.
Troubleshooting
If the stain is still there
Pick what you're seeing:
Alcohol isn't moving the tarnish
The tarnish is too heavy for a simple wipe. Move to precipitated calcium carbonate in denatured alcohol and change the cotton often.
A copper-colored spot appeared on a silver piece
Plating is wearing through. Stop polishing that area and limit future cleaning to soap, water, and gentle drying.
White residue sits in the crevices
Polish has dried in the recesses. Rinse it out with cotton dampened with denatured alcohol and buff dry.
Tarnish came back within weeks
Air exposure is restarting the reaction. Apply a thin coat of microcrystalline wax or store the piece wrapped in a tarnish-inhibiting cloth.
When to call a professional
Valuable, antique or heavily worn pieces are the ones to pause on. Before any stronger treatment, have a specialist look at them, because removing plating, gilding or a patina lowers value permanently.
Questions
What is the fastest and best way to clean tarnished silver?
The quickest safe start is cotton dampened with denatured alcohol, wiped over the tarnish and changed often as it darkens. If that doesn't lift the tarnish, move to the set-in method, which is slower but stronger.
How do I clean metal without removing its patina?
Check first whether the layer is an intended patina, because polishing destroys it. Then wash off only the dirt with a mild soap-and-water solution and leave the patina in place.
Can I use toothpaste on tarnished silver?
No, toothpaste hasn't been shown to clean silver safely, so use denatured alcohol on cotton for light tarnish. Use denatured alcohol on cotton for light tarnish, and the set-in method for heavy tarnish instead.
Can I use steel wool on chrome?
No, steel wool scratches the chrome surface, so save it for rust on bare steel tools. On chrome, stick with a soap-and-water wash and a cleaner made for bright metal, applied like a wax.
How do I stop cleaned silver from tarnishing again?
Wrap cleaned silver in acid-free tissue inside sealed polyethylene bags, or use a tarnish-inhibiting cloth. A thin microcrystalline wax coat also slows tarnish.
Can I use a chrome cleaner on wheels?
Not on wheels, since chrome cleaner, metal cleaner and polish are not for wheels and wheel covers. Use soap and water, and if that fails, an acid-free wheel cleaner approved for your wheel type in the owner's manual.
