Caring for Your Costa Sunglasses:
Maintenance Tips for Longevity

Taking the right steps to clean your polarized sunglasses helps ensure they function properly and are always ready for action. Here’s how to give them the care they need: 

 1. Wash your hands with soap and water and dry them thoroughly. 
 2. Rinse your Costas with clean lukewarm water to remove any loose debris. 
 3. Apply a small amount of mild lotion-free soap to the sunglass lenses. Gently rub the soap across the front and back lens surfaces and frames. 
 4. Rinse your Costas again to remove all the soap and any remaining residue. 
 5. Use a lint-free microfiber cloth to carefully dry the lenses and frames. 

Cleaning sunglasses correctly isn’t just about maintaining their optical clarity — it’s also about ensuring their longevity. With proper eyewear maintenance, your Costas can help keep you focused and ready for whatever comes your way.  

Now that you know the best way to clean sunglasses, it’s important to understand common mistakes that could put your shades at risk.  

Avoid the following when it comes to caring for your Costas:  

Materials that Can Scratch Your Lenses 

Never use materials like paper towels, tissues, or even your shirt to clean your polarized sunglasses. They’re abrasive and can damage your lenses and frames.  

Instead, always use a microfiber lens cloth. You can use the one that came with your Costa sunglasses or pick up an extra one to keep on hand. 

And remember — never wipe your sunglass lenses while they’re dry. Any dirt, sand, or other residue on the lens could grind into the surface and leave scratches.  

Harmful Chemicals 

It may seem convenient to use common household products for cleaning sunglasses. However, harsh substances like acetone, Windex, rubbing alcohol and vinegar may damage or degrade the lenses, lens coatings and frames.  

Stick to using mild soap to clean your sunglasses. For everyday maintenance, you can also use the lens cleaner from the Costa cleaning kit to keep your shades spotless. 

While it may be tempting, don’t use your breath to fog up your sunglass lenses or use your saliva to clean them. Saliva harbors bacteria that can be harmful to your eyes, so it’s best to skip this practice altogether. 

Improper Storage 

Improperly storing your sunglasses is a quick and easy way to ruin a good pair. Heat, cold and careless placement can all lead to damage. Follow these tips to avoid common storage pitfalls:  

• Avoid extreme temperatures – Leaving your Costas outside in frigid conditions or trapped in your car on a hot day can cause the frame material to warp or become brittle.  
• Avoid the dashboard – The sun beaming down through your car’s windshield can create intense heat that could seriously damage your shades.  
• Avoid wearing sunglasses on your head – This can stretch out the temples (arms) and loosen their fit, which makes them more likely to slip off and hit the ground.
