How to Clean Sunglasses Properly (Without Scratching Them)
A quality pair of sunglasses can last for years—but only if you take proper care of them. Unfortunately, many people accidentally scratch their lenses while cleaning them, often without realizing it.
Dust, sand, sunscreen, fingerprints, and everyday debris can build up on your sunglasses over time. If cleaned incorrectly, these particles can create tiny scratches that reduce clarity and shorten the life of your lenses.
In this guide, we'll explain how to clean your sunglasses properly, what cleaning methods actually work, and the common mistakes that can damage your lenses.
Why Proper Cleaning Matters
Your sunglasses are exposed to a lot every day:
- Dust
- Dirt
- Sand
- Sweat
- Sunscreen
- Fingerprints
- Air pollution
Cleaning them correctly helps:
✔ Maintain clear vision
✔ Protect lens coatings
✔ Prevent scratches
✔ Extend the life of your sunglasses
✔ Keep them looking new
What You'll Need
The safest cleaning method requires only a few simple items:
Recommended:
✔ Clean lukewarm water
✔ Mild dish soap (lotion-free)
✔ Microfiber cleaning cloth
✔ Lens-safe cleaning spray (optional)
Avoid using harsh household cleaners.
Step-by-Step: How to Clean Sunglasses Properly
Step 1: Rinse Away Loose Dirt
Before touching the lenses, rinse your sunglasses under lukewarm running water.
This removes:
- Dust
- Sand
- Dirt particles
Skipping this step can cause debris to rub against the lens surface and create scratches.
Tip:
Never wipe dusty lenses while they're dry.
Step 2: Apply a Small Amount of Mild Soap
Place a tiny drop of mild dish soap on your fingertips.
Gently clean:
- Front and back of lenses
- Nose pads
- Frame arms
- Hinges
Avoid soaps containing:
❌ Moisturizers
❌ Abrasives
❌ Strong fragrances
These can leave residue on lenses.
Step 3: Rinse Thoroughly
Rinse away all soap residue using clean water.
Make sure:
✔ No soap remains on the lenses
✔ No residue remains around hinges or nose pads
Leftover soap can create streaks.
Step 4: Dry with a Microfiber Cloth
Use a clean microfiber cloth designed for eyewear.
Gently pat and wipe dry.
Microfiber cloths are designed to:
✔ Lift oils
✔ Remove fingerprints
✔ Reduce scratching risk
Avoid excessive pressure while drying.
Best Lens Cleaning Sprays
Lens-safe cleaning sprays can be helpful for quick cleanups.
Look for products specifically designed for:
✔ Eyeglasses
✔ Sunglasses
✔ Coated lenses
Always follow manufacturer instructions.
What NOT to Use
Many everyday items can damage your sunglasses.
❌ Paper Towels
Paper fibers may appear soft but can scratch lenses over time.
❌ Tissues and Napkins
These products often contain rough fibers that can damage coatings.
❌ Your Shirt
One of the most common mistakes.
Even soft shirts can trap:
- Dust
- Sand
- Dirt
which may scratch lenses when rubbed across the surface.
❌ Household Glass Cleaners
Many household cleaners contain chemicals that can damage:
- Polarized coatings
- Mirror coatings
- Anti-reflective coatings
- UV protective coatings
Avoid products containing ammonia or strong solvents.
❌ Hot Water
Excessively hot water may damage lens coatings and frame materials.
Stick to lukewarm water whenever possible.
How Often Should You Clean Sunglasses?
For daily wear:
Light Cleaning
- Quick microfiber wipe daily
Deep Cleaning
- Soap-and-water cleaning once or twice per week
More frequent cleaning may be needed if you:
- Visit the beach
- Exercise outdoors
- Use sunscreen regularly
- Ride motorcycles or bicycles
Special Care for Polarized Lenses
Polarized lenses often include additional coatings.
To protect them:
✔ Use only microfiber cloths
✔ Avoid harsh chemicals
✔ Store them in a protective case
Proper cleaning helps preserve glare-reduction performance.
Special Care for Mirror Lenses
Mirror coatings sit on the outer lens surface and require extra care.
Recommendations:
✔ Rinse before wiping
✔ Clean gently
✔ Avoid abrasive materials
Mirror coatings can scratch more easily than standard lenses.
How to Store Sunglasses After Cleaning
Even perfectly cleaned sunglasses can become scratched if stored incorrectly.
Best Practice
Store sunglasses in:
✔ A hard-shell case
✔ A microfiber pouch
Avoid:
❌ Throwing them into bags
❌ Leaving them loose in vehicles
❌ Placing them lens-down on surfaces
