How to Clean and Care for Your Sunglasses: Tips to Keep Them Scratch-Free

Quick answer

To clean your sunglasses safely, rinse them under lukewarm water, apply a drop of mild dish soap, and gently wipe with a microfiber cloth. Avoid using your shirt or paper towels, as they can leave scratches. Always store your sunglasses in a hard case when not in use to prevent damage.

Sunglasses are more than just a fashion accessory; they protect your eyes from harmful UV rays and reduce glare. But if they're covered in smudges, scratches, or dirt, they can't do their job properly. Many people unknowingly damage their sunglasses by cleaning them the wrong way, using rough materials, or skipping proper storage.

This guide will walk you through the best methods to clean and care for your sunglasses, helping you keep them scratch-free and functional for years. Whether you have prescription glasses or polarized shades, these tips work for all types of lenses.

Why Proper Cleaning Matters for Your Sunglasses

Your sunglasses face a lot: sunscreen, sweat, dust, and fingerprints. If you clean them with dry tissues or your clothing, you risk grinding those particles into the lens, causing tiny scratches that can't be repaired. Over time, scratched lenses reduce clarity and can even cause eye strain.

Using a microfiber cloth and a gentle cleaning solution is the safest way to remove debris without harming the lens coating. Microfiber traps particles rather than dragging them across the surface, making it the ideal material for glasses care.

• Always handle sunglasses by the frame, not the lenses, to avoid transferring oils from your fingers.
• Avoid using ammonia-based cleaners, which can strip anti-reflective or UV coatings.

Step-by-Step: How to Clean Your Sunglasses

1. Rinse your sunglasses under lukewarm water to remove loose dust and dirt. This step is crucial because wiping dry lenses can cause scratches.

2. Put a drop of mild dish soap (like Dawn) on your fingertips and gently rub both sides of the lenses and the frame. Avoid using moisturizing soaps, as they can leave residue.

3. Rinse thoroughly under lukewarm water to remove all soap.

4. Shake off excess water, then dry with a clean microfiber cloth. Use soft, circular motions. If your glasses are particularly dirty, repeat if needed.

5. For stubborn spots like sunscreen or grease, use a lens cleaning solution specifically designed for glasses. Spray it on the lens and wipe with a microfiber cloth.

• Never use hot water, as it can damage lens coatings or warp frames.
• If you're between cleanings, use a microfiber cloth with a dry wipe to remove smudges.

How to Properly Store Your Sunglasses to Prevent Scratches

Storage is just as important as cleaning. When you toss your sunglasses into a bag or purse without protection, they can get scratched by keys, coins, or makeup. A hard case provides the best protection against impacts and scratches.

If you don't have a hard case, use a soft pouch, but be cautious—soft pouches don't protect against pressure or accidental drops. Always place your sunglasses with the lenses facing upward to avoid scratching the inner surface.

Keep your sunglasses out of extreme heat, like a car dashboard, as high temperatures can warp frames and damage lens coatings.

• Consider a hard-shell case for travel or daily storage.
• If your glasses came with a cloth, use it as a barrier between the lenses and other objects.

Common Mistakes That Cause Scratches and Damage

Using your t-shirt, tissue, or paper towel to clean your lenses is one of the most common mistakes. These materials are not designed for delicate optics and often leave micro-scratches. Even if you don't see them immediately, they accumulate over time.

Another mistake is using your breath to fog up the lenses before wiping. While it might seem convenient, breath doesn't remove oils or grit effectively, and it can leave a residue on certain coatings.

Finally, don't forget to clean your microfiber cloth regularly. A dirty cloth can hold particles that scratch your lenses. Wash it with gentle soap and water, then let it air dry.

• Invest in multiple microfiber cloths so you always have a clean one on hand.
• If your lenses are super dirty, always rinse first—don't skip this step.

The 3-Step Routine to Keep Your Sunglasses Scratch-Free

1. Rinse before you wipe: Hold your sunglasses under lukewarm water to flush away dust and small particles. This prevents those particles from scratching the lens when you wipe. Checkpoint: If you see any grit, rinse again before wiping.
2. Use a micro-bead of dish soap: Apply a tiny drop of mild dish soap to your fingers and gently clean both lenses and frame. Rinse thoroughly to remove all residue. Checkpoint: Avoid soaps with lotion or alcohol—they can leave film or damage coatings.
3. Dry with a dedicated microfiber cloth: Use a clean microfiber cloth to pat and gently wipe the lenses dry. Reserve this cloth solely for glasses to prevent contamination. Checkpoint: Store the cloth in a ziplock bag to keep it dust-free when not in use.
