Effective Ways To Save Custom Lapel Pins From Tarnishing

Most custom lapel pins are made from metal, and metal reacts to its environment. Air, moisture, and even the oils on your skin can wear down a pin’s finish faster than people expect, especially in coastal regions where salt in the air speeds up the process. That reaction is what causes tarnish, and it’s not a defect. It’s basic chemistry that every metal pin has to deal with, whether it’s a $2 giveaway pin or a $50 collectable.

What actually separates a pin that lasts from one that dulls within months isn’t the design. It’s the plating and finish underneath it and how much protection the manufacturer built in before it ever left the factory. This piece breaks down why tarnish happens, what manufacturers actually do to stop it, and what that means for you when you’re the one placing the order.

Why Custom Lapel Pins Tarnish Over Time

A pin starts to tarnish the moment its metal surface is exposed to the elements. The base metal reacts first, and everything after that speeds up or slows down depending on plating quality and how the pin is handled.

• Base metal oxidation: Iron, copper, and brass react with oxygen and moisture in the air, which leads to discolouration or a dull, cloudy surface over time.
  
• Humidity and salt air: In coastal areas of NZ, salt particles in the air accelerate the chemical reaction on exposed metal, so pins tarnish faster near the coast than inland.
  
• Sweat and skin oils: Handling a pin with bare hands transfers oils and salts that break down its protective surface layer, especially with repeated contact.
  
• Thin plating: Low-quality or thin electroplating leaves tiny gaps in the metal’s protective barrier, giving moisture a direct path to the base metal underneath.

How Manufacturers Actually Prevent It

Stopping tarnish starts at the factory, not after the pin reaches you. A well-made pin goes through several protective steps before it’s ever packaged for shipping.

Multi-Layer Electroplating

Manufacturers coat the base metal with layers of nickel, gold, or silver plating. This barrier keeps oxygen and moisture from reaching the metal underneath, which is the main reason two pins with the same design can age very differently.

Epoxy Resin Doming

A clear epoxy layer is sometimes applied over the pin’s face and baked on. It seals the surface completely, protecting both the enamel colours and the metal from air exposure and everyday scratches.

Protective Lacquer or Wax Coating

For pins with raw or exposed metal finishes, a thin lacquer or microcrystalline wax adds another layer of protection. It blocks oxidation without changing how the pin looks or feels.

Anti-Tarnish Packaging

Before pins are shipped, they’re often packed with anti-tarnish tissue, sealed poly bags, or silica gel packets. This keeps moisture away during transit and storage, so the pin arrives in the same condition it left the factory. There are also more packaging ideas for custom pins that can be used when packaging the pins.

What Tarnish Resistance Tells You About Pin Quality

The plating and coating methods above aren’t just manufacturing steps. They’re the actual difference between a pin that holds its colour for years and one that fades within months. When you’re comparing pins from different makers, the finish type tells you more about long-term quality than the design or artwork does. A pin can look sharp in a photo and still tarnish within weeks if the underlying plating is thin.

Finish Type	Surface Feel	Durability	Best Use
Soft Enamel	Textured, recessed enamel	Good, shows wear sooner on edges	Casual or everyday wear
Hard Enamel	Smooth, flush surface	Stronger resistance to scratches and tarnish	Formal or long-term display pieces

Hard enamel generally holds up better because the surface is sealed flush with the metal, leaving fewer edges for moisture or oils to catch on. Soft enamel can still perform well, but it depends heavily on the plating layer underneath it. This is one of the main things to check if you’re sourcing custom enamel pins and want them to look the same a year from now as they do on day one.

What to Ask a Custom Pin Supplier Before You Order

Most of the quality differences between pins come down to details you can’t see in a product photo. Asking the right questions before you order saves you from discovering plating issues after the pins have already shipped.

1. What type of plating is used? Nickel, gold, and silver each hold up differently, and a supplier should be able to name the exact plating without hesitation.
   
2. How thick is the plating layer? Thin plating wears through faster, even if the pin looks identical to a higher-quality one at first glance.
   
3. Is the coating confirmed in writing? A quote or spec sheet listing the plating type and finish gives you something to reference if the pins don’t hold up as expected.

A reliable custom pin supplier will answer these without pushing back, since plating details are standard information, not a trade secret.

Keep Them Dry and Handle Them by the Edge

A well-plated pin still needs basic care to stay looking new. None of this requires special products, just a couple of habits worth building into how you store and handle them day to day.

Store Them Properly

Keep pins in a sealed pouch or small box rather than an open dish or drawer. Bathrooms and laundry areas tend to hold extra humidity in the air, which speeds up tarnishing even on well-plated pins. Damp fabric works against you too. A jacket or bag left out in the rain can trap moisture against the pin’s backing for hours, and that moisture doesn’t dry out on its own once it’s sealed in.

Handle Them the Right Way

Pick pins up by the edge or backing instead of the enamel face. The oils on your fingers wear down the coating faster than normal wear would, and it adds up with repeated handling over time, especially on pins worn or moved often.

These habits matter even more for personalised lapel pins in NZ, where humidity and coastal air already put extra strain on the metal underneath.

Questions People Often Ask About Lapel Pins

1- What are lapel pins made of?

 Most lapel pins start with a base metal like iron, brass, or zinc alloy, then get plated with nickel, gold, or silver. The enamel colour is added afterwards, either hand-filled for soft enamel or polished flat for hard enamel.

2- How do you keep pins from rusting?

Store them in a dry, sealed container away from humidity, and handle them with clean, dry hands. Skin oils and moisture are the two biggest triggers for rust on exposed metal.

3- How do you remove oxidation from a metal pin?

For light tarnish, a soft polishing cloth usually works. For green copper oxidation, a mix of white vinegar and salt applied briefly with a cotton swab can lift it, though painted enamel areas should be avoided during cleaning.

4- What’s the real difference between soft and hard enamel pins?

Soft enamel has a textured surface with raised metal lines, while hard enamel is polished flat and smooth. Hard enamel generally resists scratches and tarnish better because the surface has fewer edges for moisture to collect on.

5- How do you protect enamel pins long-term?

Keep them in a velvet-lined case or pouch when not worn, avoid submerging them in water, and wipe them with a soft, dry cloth rather than anything abrasive.

Final Takeaway

Whether a pin tarnishes quickly or holds up for years comes down to two things: how well it was plated in the first place and how it’s stored afterwards. A supplier that’s upfront about plating type and thickness is usually a good sign of overall quality. From there, keeping pins dry and handling them by the edge does most of the remaining work. There’s no complicated routine involved, just a few habits that protect the finish over time. Getting these basics right is really what separates a pin that still looks new a year later from one that doesn’t.
