Generally speaking, when you do not need to wear your sunglasses, you have put them away getting rid of the dirt and dust, especially the branded sunglasses, like Smith brand. If now you want to clean your loved Smith sunglasses, I can tell you two options, and you can choose from them. The first way, also the easiest way, is that you can take your sunglasses to the authentic Smith shop because thery can clean them for you. Pls no worries, it will as free of charge as usual. Then, if you think the shop is far away from you and you want to clean them by yourself, now and here I can tell you some simple ways to make it. A much better idea is to clean the lenses with a microfiber or lint-free cloth, which will cost you less money and time.(pls note never clean them with regular towel, paper towel, or washcloth) Hope I can help you and your loved Smith sunglasses.
