Twist the cap 1 round then pull it off.. then swirl the flat-tip of the Lens Pen across your lens in concentric, circular motions till it's acceptable clean.
I've used many cleaning methods before and I feel thatthe LensPen is by far the most effect and easy to use.
Lens tissues and even skin cloths tend to leave very tiny specks. LensPens clean using a dry carbon compound that leave virtually no reidue.
