Why Does My Gold Jewellery Tarnish? Causes and Fixes

Introduction

Gold jewellery is timeless, elegant, and an everyday staple for many women (and men, of course). But if you’ve noticed your favourite gold pieces turning dull or discoloured, you’re not alone! Tarnishing is a common issue, leaving many wondering: Does real gold even tarnish? Is it permanent? How do I keep my jewellery looking new?

If you’re frustrated by your gold losing its shine, don’t worry! In this guide, we’ll explore why gold jewellery tarnishes, how to prevent it, and the best ways to restore its brilliance.

Does Real Gold Tarnish?

Pure gold (24K) is highly resistant to tarnishing because it doesn’t react with oxygen or moisture. However, most gold jewellery isn’t made from 100% gold—it is mixed with other metals for durability and affordability.

What Causes Tarnishing?

Tarnish is a thin layer of corrosion that forms when gold alloys react with environmental elements. Here’s why it happens:

• Gold Purity – Lower-karat gold (10K, 14K, 18K) contains metals like copper, silver, and nickel, which are prone to oxidation.
• Exposure to Moisture & Air – Humidity and air pollutants cause reactions that dull gold over time.
• Body Oils & Sweat – Natural skin oils, sweat, and even pH levels can accelerate tarnishing.
• Cosmetics & Perfumes – Makeup, lotions, and sprays contain chemicals that can dull gold’s lustre.
• Household Cleaners & Chlorine – Harsh chemicals in cleaning agents and chlorinated pools can corrode gold alloys.

Pro Tip: Higher-karat gold (18K and above) is less likely to tarnish due to its higher pure gold content.

Is Tarnished Gold Permanent?

The good news? Tarnishing isn’t permanent! Unlike rust, which deteriorates metal, gold tarnish is just a surface layer that can be cleaned. With the right care, your gold jewellery can regain its sparkle.

However, excessive tarnish build-up or prolonged exposure to harsh elements can weaken gold plating or cause deeper discolouration. That’s why regular maintenance is key!

How to Remove Tarnish from Gold Jewellery

Bringing back your gold’s glow is easier than you think! Here are some safe and effective cleaning methods:

1. Dish Soap & Warm Water (Gentle Cleaning)

✔️ Mix a few drops of mild dish soap with warm water.
✔️ Soak your jewellery for 15-20 minutes.
✔️ Use a soft brush to clean crevices.
✔️ Rinse with clean water and pat dry.

2. Baking Soda & Vinegar (For Stubborn Tarnish)

✔️ Mix 1 tbsp of baking soda with ½ cup of white vinegar.
✔️ Soak gold jewellery for 5-10 minutes.
✔️ Rinse and dry with a lint-free cloth.

3. Lemon Juice & Salt (For Extra Shine)

✔️ Mix lemon juice with a pinch of salt.
✔️ Gently rub the mixture onto tarnished areas.
✔️ Rinse well and buff dry.

Avoid using abrasive cloths or hard brushes, as they can scratch your gold!

How to Keep Gold Jewellery from Tarnishing

Preventing tarnish is much easier than constantly cleaning it! Here’s how to protect your gold jewellery:

1. Store It Properly

• Keep gold jewellery in a soft pouch or jewellery box lined with fabric.
• Use anti-tarnish strips to absorb moisture and prevent oxidation.

2. Minimise Exposure to Moisture

• Remove jewellery before showering, swimming, or working out.
• Always dry jewellery completely before storing it.

3. Avoid Contact with Chemicals

• Apply lotions, perfumes, and hairsprays before putting on jewellery.
• Wear gloves when handling household cleaners or harsh chemicals.

4. Clean Regularly

• Wipe jewellery with a soft, dry cloth after each wear.
• Perform a deep clean every few weeks to prevent build-up.

FAQs

1. Why is my gold jewellery turning black?

Gold can develop a black tarnish due to sulphur exposure, sweat, or chemical reactions with cosmetics and perfumes. This is more common in lower-karat gold.

2. Can I use toothpaste to clean gold jewellery?

While toothpaste is a popular DIY method, it contains abrasive particles that can scratch gold. It’s best to stick with gentler cleaning solutions.

3. How often should I clean my gold jewellery?

For everyday pieces, cleaning once every 2-3 weeks helps maintain shine. Occasional wear pieces can be cleaned once a month.

4. Does gold-plated jewellery tarnish faster?

Yes! Gold-plated jewellery tarnishes quickly because the thin gold layer wears off, exposing the base metal underneath. Proper storage and gentle cleaning can extend its lifespan.

5. Can I wear gold jewellery every day?

Absolutely! Gold is durable, but daily wear can lead to tarnishing. Regular cleaning and proper care will keep it looking new.
