You have probably noticed a mysterious green deposit on your glasses (residue) forming around your nose pads or the hinges of your metal frames? You aren’t alone. This “green gunk” is a common problem for eyeglass wearers contributing to glasses turning green, but with the right care from Ottico Eyecare, you can keep your frames looking brand new.
In this guide, we’ll explain why this happens and how to safely restore your style.
What is the Green Deposit?
The green on your glasses is typically a form of oxidation or corrosion. It occurs when the metal components in your frames react with external elements.
The Common Culprits:
- Copper & Brass Corrosion: Most metal frames contain copper or brass alloys. When exposed to oxygen and moisture, they produce greenish compounds known as verdigris.
- Plating Wear and Tear: Over time, the gold or silver plating on your glasses can wear off at high-friction points like the nose pads. This exposes the base metal to your skin, leading to rapid oxidation.
- Sweat & Cosmetics: Human sweat contains salts and acids. When mixed with makeup, skin creams, or sunscreen, it creates a chemical reaction that accelerates the “greening” process.
- Nickel Oxidation: Some frames use nickel, which can turn a grayish-green when it reacts with the oils in your skin.
How to Safely Clean Green
Before you reach for harsh chemicals, remember that your lenses are sensitive. Follow these steps to clean your frames without damaging your prescription.
Step 1: The Gentle Wipe
Use a soft, dry microfiber cloth or a very soft-bristled toothbrush to gently brush away any loose green flakes or debris.
Step 2: Mild Soap & Water
Mix warm water with a single drop of mild, lotion-free dish soap. Dampen a cloth and rub the affected area gently. Rinse with lukewarm water and dry thoroughly with a clean cloth.
Step 3: For Stubborn Stains
If the green buildup is stuck:
- Isopropyl Alcohol (70%): Apply a small amount to a cotton swab and dab the metal part only. Avoid touching the lenses, as alcohol can damage certain lens coatings.
- Vinegar Solution: A 50:50 mix of white vinegar and water can help dissolve verdigris. Test a small, hidden area first to ensure it doesn’t dull the frame’s finish.
Step 4: Professional Servicing
If the metal is “pitted” (has small holes) or the plating is completely gone, home cleaning won’t fix the underlying issue. Bring your frames to Ottico Eyecare in Nairobi, where we can professionally clean or replace your nose pads.
Prevention: How to keep off glasses turning green
Prevention is easier than a deep clean. Here is how to keep your Ottico frames sparkling:
- Daily Maintenance: Wipe your frames every evening with a microfiber cloth to remove the day’s sweat, salt, and oils.
- Upgrade Your Nose Pads: Switch to hypoallergenic silicone nose pads. These provide a barrier between the metal and your skin.
- Choose Better Materials: If you have acidic skin or sweat heavily, consider frames made of Titanium, Stainless Steel, or Acetate (high-quality plastic). These materials are naturally resistant to corrosion.
- Avoid Chemicals: Remove your glasses before swimming in chlorinated pools or applying heavy face creams and perfumes.
Dealing with Green Stains on Your Skin
If your glasses leave a green mark on your nose, don’t panic! It is temporary and non-toxic.
- Removal: Simply wash with warm soap and water. A paste made of baking soda and water can also gently exfoliate the stain away.
- When to worry: If the green stain is accompanied by an itchy rash or redness, you may have a nickel allergy. Visit us at Ottico Eyecare to explore our nickel-free frame collections.
If your frames are heavily corroded or the plating is peeling, it might be time for an upgrade. A corroded frame can become brittle and break when you least expect it.
