Sunglass lenses become dirty with daily wear, regardless of the type of finish on the lens. This is especially true when it comes to sunglasses. You’re always taking them off and putting them back on, so they’re bound to get smudged.

A common tactic for cleaning sunglasses is to moisten the lens with your breath and then wipe them with a shirt or napkin. Avoid this gross practice. Rather than helping, it can smear dirt spots and scratch your lenses. Here’s what you really need to know:

How to Clean Sunglasses

The Dos and Don'ts of Sunglass Cleaning Avoid this: Do this: Using your breath as a cleaning product only smears dirt around your lenses. Drying your lenses with a paper towel, napkin, or your shirt will just scratch them. Materials Needed Warm, running water Dish soap (without added lotions) Lint-free cloth Moisten the lenses, arms, and frame with warm tap water. Dab a drop of soap onto your lenses, and gently rub into lenses, frame, and arms using your thumb or forefinger. Rinse glasses delicately with warm water. Dry with a lint-free cloth. Special note: Lens cleaner spray can take the place of soap and water. Just be sure the spray is safe for anti-reflective and coated lenses. Brought to you by Sunglass Warehouse

Avoid drying with paper products because their wood content can scratch the lenses. Use a liquid soap that doesn’t have added lotions because they coat the lenses with a milky film. Clear dishwashing soap (such as Dawn) works best. Soap removes body oil not only from the lenses, but from the nose pads, hinges, and screws. Don’t forget these areas when cleaning, because body oil can loosen them and cause future breakage. Now go flash those shiny shades at the world!
