Tips to Help Clean Green Gunk on Jewellery

If you own a piece of jewellery, for sure you have experienced getting it out of your jewellery box after a long time of not using it, only to discover that it has green gunk all over it. This green gunk can appear on the clasps of necklaces and bracelets, on the clips of earrings, and just about anywhere on your valuable jewellery. Any metal surface on your jewellery is not safe from this unsightly green gunk.

You will also notice that parts of the jewellery that have the most green gunk are parts that often come in contact with your skin. These parts are more prone to accumulating sweat and dirt, as well as cosmetic products that you apply.

If you’re reading this, you’re probably one of those people who love wearing jewellery but hate seeing the green gunk all over it. Getting this green gunk on your precious pieces does not mean that you have to throw them away Fortunately, there is a way to remedy this. In this article, you will discover effective ways to help clean green gunk on jewellery.

What is That Green Gunk Called, Anyway?

 

The green gunk that you can see on jewellery and other metal pieces is called verdigris. It’s the natural patina that forms when copper oxidises. Verdigris also forms when it comes in contact with moisture and other forms of pollutants over time. These pollutants include bodily fluids like sweat and oils, as well as cosmetic and hair products.

This green gunk is not only unsightly but also a pain to clean, especially from exquisitely designed antique costume jewellery. It’s also a corrosive agent, which means that it eats away small bits of metal if you don’t remove it right away.

Verdigris can grow on pure and alloy forms of bronze, brass, and copper, as well as items that are gold or silver plated. When a small part of the plating is worn very thin, chipped, or removed, the surface is a ripe breeding ground for verdigris to form. If you store your good jewellery with a piece that already has verdigris on it, it will easily get infected with this green gunk as well.

How Your Skin and Habits Affect Green Gunk on Jewellery

Everyone’s skin is different, and personal habits play a big role in how quickly green gunk forms on jewellery. If your skin is more acidic (a lower pH), or if you tend to sweat a lot, your rings, necklaces, or bracelets are more likely to react with moisture and develop green tarnish on jewellery. Frequent use of lotions, perfumes, or hair products can also speed up this reaction, as these substances often contain chemicals that cause jewellery to turn green on the skin. Even your diet can have an effect, since certain foods can change the acidity of your sweat and lead to green stains from jewellery. That’s why some people notice green discoloration on jewellery more often than others, even when wearing the same types of pieces, such as gold plated earrings  or sterling silver earrings.

Tips to Help Clean Green Gunk on Jewellery

1. You can help clean green gunk on jewellery with the use of a toothpick.

Scrape small amounts of the green gunk from tiny spots or hard to reach areas of your jewellery. This will work in the tiniest or tightest spots, like the clasps or chains.

2. If you’re trying to clean a bigger area, you can replace the toothpick with a pencil eraser or a toothbrush.

Use a brush with soft bristles so as not to scratch the surface of your jewellery, especially if they are vintage or antique pieces. Use it dry and brush it on the green gunk, removing as much as you can without damaging the jewellery. Erasing the green gunk with a pencil eraser can also do the trick, especially if the green gunk is not old and tough.

3. You can also use metal polish to help clean green gunk on jewellery.

After brushing off as much green gunk as you can with your toothpick, toothbrush, and pencil eraser, you can move on to using metal polish. Metal polishes can be purchased in most hardware stores. They are slightly abrasive creams that will help clean green gunk on jewellery as well as dirt from other kinds of metals. Just squeeze a pea-sized amount of the polish on a soft and clean cloth and rub it on your jewellery with green gunk.

Scrub it for about 30 seconds and check for any changes. You may need to do this a couple of times depending on how much green gunk there is. Finish polishing your jewellery pieces until you’re satisfied with how it looks. If using metal polish does not completely remove the green gunk, don’t panic. There are still some home chemical treatments which you can try.

4. Vinegar can help clean green gunk on jewellery.

You should know that vinegar is not only used for cooking but for many other cleaning purposes as well. Vinegar can be used to clean green gunk on your jewellery.

Pour some white vinegar in a cup or a bowl and soak your verdigris-filled jewellery for about half an hour. After the half hour is through, you can pull your jewellery out and brush it again with a toothbrush. Rinse it well in water and then dry it with a soft and clean cloth.

However, don’t do the vinegar soak for jewellery with rhinestones that have foil backings, pearls, or fake pearls. If the green gunk is only present in some parts of your jewellery, you can still do the vinegar method. But instead of soaking the whole thing in the vinegar, you can use a cotton ball instead.

Dip the cotton ball in the vinegar and leave it on the part of the jewellery that only has verdigris. This will protect the other parts of your jewellery that should not be exposed to vinegar.

5. Did you know that ketchup can also be used to help clean green gunk on jewellery?

Ketchup is also acidic and can stay in place. The same caution with using vinegar should be taken when using ketchup.

Lay your jewellery on a paper towel and put a little ketchup on the green gunk. Allow it to sit for about 30 minutes. Rinse it well afterwards and allow it to dry thoroughly.

Things That You Can Do to Prevent Green Gunk Buildup

 

Proper storage of your precious jewellery will prevent damage from green gunk. Try not to expose them to moisture. Make sure that before you put your jewellery away, there’s no residue makeup, dirt, or moisture present.

It’s strongly advised that you don’t pile your jewelry together and leave it untouched or unused for months or years.

Make sure that you get your jewellery out of storage once in a while even if you don’t plan on using or wearing them. This will allow you to check them for green gunk in its earliest stages. The sooner you catch early signs of verdigris, the sooner you can start removing it!

Verdigris occurs when jewellery is not properly protected or cared for against the elements. In order to avoid verdigris, your jewellery should be kept in a cool and dry place. Never store them when they’re damp or dirty. If you can get the small silica gel packs, make sure you store your jewellery alongside them to absorb any excess moisture.

If you’re hitting the beach or hanging out in the pool, it’s best to remove your jewellery first or not wear them at all to avoid water damage. Verdigris can spread from one piece of jewellery to the next. This is why it’s best to store each piece separately.

Green Stuff on Earrings & Jewellery: Frequently Asked Questions

Noticed a green residue around your earrings, earring posts or other jewellery? It can look alarming, but in most cases the explanation is quite straightforward. The green build-up is usually connected to the way certain metals react with moisture, air, skincare products and everyday wear.

Here are some of the most common questions about green stuff on earrings and jewellery.

Q: What is the green stuff on earrings?

The green stuff on earrings is usually a form of metal oxidation or corrosion, often involving copper.

Many jewellery metals and alloys contain a small amount of copper. When copper is exposed to moisture, oxygen, sweat, skincare products or other substances, it can react and form green-coloured compounds on the surface.

This green residue is sometimes loosely referred to as verdigris, although technically verdigris describes particular types of copper corrosion.

The build-up may also contain everyday residue such as:

• sweat and skin oils

• soap

• moisturiser

• makeup

• shampoo or conditioner

• dead skin cells

• dust and other debris

So what looks like simply "green gunk" can actually be a combination of metal oxidation and accumulated residue from wear.

Q: Why is there green stuff on my earrings?

If you are wondering why there is green stuff on your earrings, moisture is one of the biggest factors.

Earrings are particularly susceptible because the posts, backs and areas around the piercing are frequently exposed to sweat, natural skin oils and moisture.

Green build-up can develop more quickly when earrings are:

worn while showering or swimming, exposed frequently to perfume or skincare products, stored while still damp, worn during exercise, or left uncleaned for long periods.

Warm and humid conditions can also accelerate reactions between metal and moisture.

Q: Why do my earrings have green stuff even though they are sterling silver?

Sterling silver is not 100% pure silver. Standard sterling silver contains 92.5% silver, with the remaining 7.5% typically consisting of other metals, commonly including copper.

That copper content helps make sterling silver stronger and more practical for jewellery, because pure silver is comparatively soft.

Under certain conditions, the copper within a sterling silver alloy can contribute to discolouration or surface residue. Sterling silver is also more commonly associated with darker tarnishing, so the exact colour of any build-up can depend on the alloy, environment and substances the jewellery has contacted.

Q: What is the green stuff on jewellery?

The green stuff on jewellery is most commonly associated with copper reacting with its surrounding environment.

Copper may be present in the jewellery itself, in a metal alloy underneath plating, or as part of sterling silver.

When copper reacts with oxygen, moisture, acids, salts and other substances, different copper compounds can form. Some of these have a noticeable blue-green or green appearance.

This is why green residue can sometimes appear on earrings, rings, necklaces, clasps and chains.

Q: What is the green stuff on my jewellery if it is gold plated?

Gold-plated jewellery consists of a layer of gold applied over another metal.

Gold itself is highly resistant to corrosion. However, as plating gradually experiences normal wear, the underlying metal can become more exposed.

If that underlying metal contains copper, moisture and chemicals may eventually cause green oxidation to develop.

This does not necessarily mean the piece has suddenly become poor-quality jewellery. Plating is a surface treatment and, depending on its thickness, how frequently the jewellery is worn and how it is cared for, it can naturally wear over time.

Keeping plated jewellery away from prolonged moisture, perfume, lotions and household chemicals can help extend the life of the finish.

Q: What causes green build-up on metal?

Green build-up on metal generally develops because of a chemical reaction between the metal and its environment.

Common contributors include moisture, oxygen, perspiration, salt, humidity, cosmetics, perfume, cleaning products and acidic substances.

Copper-containing metals are particularly known for developing green corrosion products.

Interestingly, this is the same broad reason aged copper objects can gradually develop their characteristic green patina.

Q: Is green stuff on earrings the same as your skin turning green?

They are related, but they are not exactly the same thing.

Green stuff on the earring refers to residue or corrosion that has developed on the jewellery itself.

Green skin from jewellery occurs when metal compounds transfer from the jewellery onto the skin.

Copper is often responsible for this temporary green staining. Sweat, skin chemistry and moisture can make the effect more noticeable.

Green skin staining is generally different from an allergic reaction. If you experience persistent itching, swelling, pain, redness or irritation around a piercing, however, stop wearing the jewellery and seek appropriate medical advice.

Q: How do you prevent green stuff building up on earrings?

Good jewellery care can significantly reduce the likelihood of green residue developing.

Keep earrings as dry as possible and remove them before swimming, showering or exercising. Apply perfume, hairspray, moisturiser and cosmetics before putting your jewellery on and allow those products to dry first.

After wearing your earrings, gently wipe them with a clean, soft cloth before storing them.

Store jewellery somewhere dry rather than leaving pieces in bathrooms or other humid environments, and keep individual pieces separated where possible to reduce scratching and unnecessary wear to plated surfaces.

Regular, gentle cleaning also helps prevent oils and cosmetic residue from accumulating around earring posts, backs and small crevices.

Q: Can you clean green stuff off earrings?

In many cases, yes, but the correct cleaning method depends on the jewellery's material and finish.

Avoid aggressively scrubbing jewellery or automatically reaching for strong acids, abrasive cleaners or household chemicals. Although these may remove corrosion, they can also damage delicate finishes, gemstones and gold or rhodium plating.

For plated jewellery especially, gentle cleaning is important because excessive polishing can gradually remove the plated surface itself.

Start with a soft, dry jewellery cloth. If further cleaning is required, follow the care instructions appropriate for the specific metal, plating and stones used in the piece.

Q: A final note on green jewellery residue

Seeing green stuff on your earrings or jewellery doesn't automatically mean your jewellery is ruined. It is often the visible result of metals interacting with moisture, skin chemistry and everyday products.

Understanding what causes the green build-up, keeping jewellery clean and dry, and caring for different metals appropriately can help your favourite earrings stay looking their best for considerably longer.
