Procedure

1. Inspect the components for lint, particulates, and sample buildup or coatings using a magnification device.
2. Use the 6,000 grit MICRO-MESH polishing swabs to clean the bore of the Exit lens, MP00 RF rods, and L0 lens.
3. Sonicate the components in either a 50:50 solution of methanol-water or a 1% solution of Liquinox in water for 10 minutes.
4. If a sonicator is not available, do the following:
1. To clean the Exit lens, use a soft toothbrush with a 1% solution of Liquinox in water.
4. Rinse the components thoroughly with water.
5. Sonicate the components in water for 10 minutes.
6. Sonicate the components in methanol for 10 minutes.
7. Rinse the components with methanol.
8. Dry the components thoroughly with nitrogen gas.
9. Use a magnification device to inspect the components (bore of the orifices) for residual lint or particulates.
10. If present, use plastic tweezers or a similar tool to remove them.
