Oxidation on Sunglasses: What It Is and How to Remove It Safely
Table of Contents
Noticed a white or greenish residue on your metal frame? That’s oxidation on sunglasses, a common issue caused by moisture and skin contact. Here’s how to clean it effectively and keep your eyewear in top shape.
What causes oxidation on sunglasses?
Oxidation occurs when metal components of your sunglasses, such as hinges or arms, react with oxygen and moisture, often from sweat, humidity, or even salty air.
This reaction creates discolouration, flaking, or a chalky white/green film, particularly on metal alloy frames or around screws and joints.
While oxidation is mostly a cosmetic issue, if left untreated, it can weaken the structure of your sunglasses or make them uncomfortable to wear.
How to remove oxidation from sunglasses safely
To clean oxidation without damaging your frames:
- Use a soft cloth or cotton swab dipped in a mix of warm water and mild dish soap. Gently scrub affected areas — for more eco-conscious care, check out our Eco-Friendly Glasses Cleaning Tips.
- For persistent oxidation, apply a small amount of white vinegar or lemon juice, letting it sit for a few minutes before wiping it off.
- Avoid abrasive tools or harsh chemicals, which could scratch the surface or remove protective coatings.
Tip: After cleaning, dry your sunglasses thoroughly to prevent further oxidation.
Can you prevent sunglasses from oxidising?
Yes—prevention is key. Here’s how to reduce oxidation risks:
- Wipe down your frames regularly with a dry microfiber cloth after use
- Avoid storing sunglasses in humid or damp environments (e.g. gym bags or beach towels)
- Keep them in a protective case when not in use
- Consider frames made from oxidation-resistant materials like acetate or titanium
These small habits can significantly extend the life of your favourite shades.
When oxidation becomes irreversible
If the oxidation has corroded or weakened the frame, especially on hinges or screws, professional repair or frame replacement may be necessary. If your frames feel loose, you might also find these simple hacks to tighten sunglasses helpful.
