You finished a grueling workout, threw your sports sunglasses in your gym bag, and forgot about them. The next time you pull them out, they are covered in a crusty, white film of dried sweat, sunscreen, and salt.
Before you grab the bottom of your t-shirt and start scrubbing, stop! You could destroy your expensive lens coatings in seconds. Here is the safe, 3-step way to clean your sports eyewear.
Why T-Shirts and Dish Soap are Dangerous
Your sports lenses have sensitive exterior coatings, including anti-scratch, anti-reflective, and hydrophobic layers.
-
The T-Shirt Trap: Dry clothing fabrics contain microscopic wood fibers and dust particles that act like sandpaper, micro-scratching your lenses.
-
The Soap Mistake: Many household dish soaps contain harsh degreasers or citrus additives that can literally strip away or bubble mirror coatings over time.
The Safe 3-Step Cleaning Routine
-
Step 1: Rinse with Lukewarm Water: Before touching the lens, run them under a gentle stream of lukewarm tap water. This flushes away coarse salt crystals, dirt, and sand particles that would otherwise scratch the lens during wiping.
-
Step 2: Use a Dedicated Lens Spray or Mild Soap: Use a cleaning spray specifically formulated for coated optics. If you don't have any, a single drop of basic, lotion-free dish soap (like blue Dawn) works safely. Gently work it around the lenses using your fingertips.
-
Step 3: Dry with a Microfiber Cloth Only: Shake off the excess water and wipe the frames dry using a clean microfiber cloth (the silky pouch or cloth that came with your glasses). Never use paper towels, tissues, or napkins, as they are far too abrasive.
