Oils, make-up, sunscreen and other products like to jump from our faces onto our lenses making them very hard to clean sometimes. We suggest washing your glasses/lenses with Dawn soap! This breaks down whatever is on the lenses leaving you crisp and clean lenses. We also like to use not one, but TWO cleaning cloths. One cloth to get the excess water off the lenses and the second to polish! If you would like to learn more please head over to our blog to see a demonstration of our cleaning process.
