Stop Wiping Your Shades With Hand Sanitizer

We have all been there: you are driving down the highway, the glaring Canadian sun is blinding, and your favourite sunglasses are covered in oily fingerprint smudges. You reach into your centre console, grab the nearest bottle of hand sanitizer, and prepare for a quick, sterile wipe down. Stop right there!

Why This Common Habit Ruins Your Eyewear

Contrary to the popular belief that hand sanitizer is perfectly safe for a quick lens sterilization, eye care authorities are issuing massive warnings on what not to do with your expensive sunglasses. That innocent squirt of sanitizer is actually a chemical death sentence for your lenses.

The Chemistry of Destruction

The culprit? Ethyl alcohol. Common sanitizers are packed with high concentrations of ethyl alcohol designed to kill bacteria. However, when this chemical comes into contact with high-end optical lenses, it instantly breaks down the chemical bonding of polarized films and anti-reflective coatings. Left overnight, even a tiny amount of hand sanitizer residue permanently dissolves these critical UV-blocking layers. Your lenses will peel, become permanently cloudy, and completely lose their ability to protect your eyes from harmful ultraviolet rays.

What You Should Do Instead

  • Use Mild Soap: A tiny drop of standard dish soap and lukewarm tap water is the safest bet to cut through grease.
  • Keep Microfiber Handy: Store a clean, dry microfiber cloth in your glovebox. Never use paper towels or your t-shirt, which can cause severe micro-scratches.
  • Dedicated Cleaners: If you need an on-the-go spray, only use alcohol-free lens cleaners specifically formulated for polarized glasses.

Do not let a two-second cleaning hack destroy your expensive shades. Protect your investment, and more importantly, protect your vision from the harsh summer rays!
