In a Nutshell:
Yes, costume jewelry can be cleaned, but only with gentle methods. Harsh cleaners, soaking and aggressive polishing can strip plating, cloud stones and loosen settings. Light surface cleaning and dry methods are usually safest.
Costume jewelry is designed to be worn, but not necessarily to last forever. Unlike fine jewelry, it is often made from plated metals, glass, resins and synthetic stones that react poorly to moisture, friction and chemicals. That does not mean costume jewelry cannot be cleaned. It means it needs to be cleaned carefully.
Knowing what can be cleaned, how often and with which methods makes the difference between extending the life of a piece and permanently damaging it. This guide explains what works, what does not, and what we generally recommend based on material and construction.
Costume jewelry typically uses base metals coated with a thin layer of gold, silver or other finishes. Stones are often glued rather than set, and many pieces include painted or sealed surfaces. These construction choices keep costs low but also make the jewelry vulnerable.
Water can seep into glued settings. Alcohol and solvents can dissolve finishes. Abrasion removes plating quickly. Once damage occurs, it is rarely reversible.
This is why costume jewelry requires a different approach than solid gold or sterling silver.
Before discussing safe methods, it is important to be clear about what not to do.
Do not soak costume jewelry in water. Even short soaking can loosen glue and cause clouding behind stones.
Avoid ultrasonic cleaners. The vibrations can break adhesive bonds and cause stones to fall out.
Do not use silver polish, toothpaste or abrasive cloths. These remove surface finishes and expose base metal.
Avoid harsh household cleaners, including vinegar, ammonia and bleach. These can discolor metal and damage coatings.
If a piece is already flaking, peeling or showing exposed base metal, cleaning may worsen the appearance rather than improve it.
For most costume jewelry, the safest approach is dry or minimally damp cleaning.
A clean, dry microfiber cloth is often all that is needed to remove skin oils and surface residue. Gently wipe the piece without pressure, focusing on areas that contact skin.
This method is safe for almost all costume jewelry and should be your first step.
If oils or residue remain, lightly dampen a cloth with plain water. The cloth should be barely moist, not wet. Wipe carefully and immediately dry the piece with a separate cloth.
Avoid allowing moisture to collect near joints, hinges or glued stones.
Dry or slightly damp cotton swabs can help clean crevices and detailed areas. Use gentle rolling motions rather than scrubbing.
Never press swabs into stone settings or seams.
Only use a drop of very mild dish soap if the jewelry has no glued stones, no painted surfaces and no visible wear. This applies to some modern fashion jewelry but not most vintage pieces.
Even then, apply soap to the cloth, not directly to the jewelry, and dry immediately.

Not all costume jewelry materials behave the same way.
Plated metals are the most vulnerable. Once plating wears off, it cannot be restored through cleaning.
Rhinestones and glass stones are usually glued. Moisture behind the stone can cause fogging or discoloration.
Resin, acrylic and plastic stones can scratch or cloud easily and should only be cleaned dry.
Painted or sealed finishes can lift or smear when exposed to moisture or solvents.
If you are unsure of the materials, assume the most fragile option and clean conservatively.
Light cleaning after wearing is better than deep cleaning later. Wiping jewelry with a dry cloth before storing it helps prevent buildup and corrosion.
Avoid frequent damp cleaning. The more often moisture touches the piece, the greater the risk of long term damage.
Storage also plays a role. Keeping jewelry dry, separate and away from heat and sunlight reduces the need for cleaning.
Sometimes, costume jewelry looks dull or tarnished because the finish is wearing away, not because it is dirty. In these cases, cleaning will not restore shine and may worsen the appearance.
Loose stones, peeling plating and green or dark discoloration usually indicate structural wear. At that point, the best option may be repair, repurposing or replacement rather than cleaning.
For sentimental or high-quality pieces, a professional jeweler may be able to stabilize or replate the item, but this is often not cost-effective for typical costume jewelry.
Costume jewelry used for cosplay or stage wear often experiences more stress than everyday accessories. Sweat, friction and extended wear accelerate damage.
For these pieces, minimal cleaning and careful storage are especially important. Consider using duplicates for heavy use or display and reserving more delicate pieces for limited wear.
In some cases, sealing the back of stones or reinforcing settings before wear can help extend the life of costume jewelry used in costumes.
Costume jewelry can be cleaned, but it requires restraint. Gentle, dry methods are safest, and moisture should be used sparingly if at all. If a piece shows signs of wear beyond surface dirt, cleaning may not help and could cause permanent damage.
Treat costume jewelry as decorative rather than durable, and focus on preserving what is already there rather than trying to restore it to new condition.
Can costume jewelry be cleaned safely?
Yes, costume jewelry can be cleaned safely if gentle methods are used. Dry or slightly damp cloth cleaning is usually safest, while soaking and harsh cleaners should be avoided.
What is the safest way to clean costume jewelry?
The safest method is wiping with a clean, dry microfiber cloth. This removes oils and surface residue without damaging plating or glued stones.
Can you use soap and water on costume jewelry?
Soap and water should only be used in limited cases and very sparingly. Many costume jewelry pieces contain glued or plated elements that can be damaged by moisture.
Why does costume jewelry turn green or dark?
Discoloration usually happens when base metals react with moisture, sweat or air after the plating wears away. Cleaning cannot reverse this type of damage.
Can tarnished costume jewelry be restored?
In most cases, no. Tarnish on costume jewelry often means the finish is deteriorating. Cleaning may improve appearance slightly but will not restore lost plating.
How often should costume jewelry be cleaned?
Light cleaning after wearing is best. Frequent deep cleaning increases the risk of damage, especially for older or heavily plated pieces.
