1. Using a magnification device, inspect the components for any lint, particulates, and
sample buildup or coatings.
2. For 10 minutes, sonicate the components in either a 50:50 solution of methanol/water or
a 1% solution of Liquinox in water.
3. Using the 6000 grit MICRO-MESH polishing swabs, clean the bore in each lens.
4. Rinse the components thoroughly with water.
