Apply a small amount with your finger to one side of the lens, then move to the other side, then the back side lens, then the other side back side.
Let it COMPLETELY dry on the lenses (similar to wax on paint), wipe off with a microfiber or cotton cloth.
I recommend using the product every morning before a shooting event. You can use less, however the more you use Z-Clear the better it will work. Free Shipping
