Drop and drag cleaning method
This method of cleaning prevents excessive pressure from being applied to the lens surface, which can cause foreign
objects to scratch the lens. This cleaning method works best on the flat side of the lens.
2. Put a piece of lens tissue on the flat surface of the lens and put three or four drops of the Isopropyl alcohol on
the lens tissue.
3. Slowly drag the tissue over the lens allowing the Isopropyl alcohol to evaporate as the tissue is pulled across
the surface. Inspect the lens for contamination as described earlier and repeat this step if necessary.
