A common tactic for cleaning sunglasses is to moisten the lens with your breath and then wipe them with a shirt or napkin. However, this should be avoided because it can smear dirt spots and scratch your lenses. Read on for some tips to keep your shades in good form:
The best way to clean sunglasses is with a drop of liquid soap and warm water.
1. Moisten the lenses and frame with warm tap water.
2. Dab a drop of soap on thumb or forefinger and gently rub into the lenses and throughout frame and arms.
3. Rinse glasses delicately with warm water.
4. Dry with a lint-free cloth.
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 dish washing soap (such as Dawn) works best. Soap removes body oil not only from the lenses, but the nose pads, hinges and screws. Don’t forget these areas when cleaning, because body oil can loosen them and cause future breakage.
