Promising review: "Unbelievable! I have been using lens spray for years for my coated prescription glasses and my professional cameras. Wipe, wipe, breathe on, wipe, wipe 'til they are finally clean. So I received a small 3" square lens cleaning microfiber cloth with a new camera lens and tried it on my glasses. In all honesty, I didn't think that a dry cloth would clean the glasses. Was I wrong!? I was astounded, to say the least." —Alan Arnold
