Use an abrasive slurry of alumina powder and reagent-grade methanol on
a cotton swab. Use enough force to remove all discolorations. Polishing the
parts is not necessary; small scratches will not harm performance. Also,
abrasively clean the discolorations where electrons from the filaments
enter the source body.
Ensure all abrasive residue is rinsed away before ultrasonic cleaning. If
the methanol becomes cloudy or contains visible particles, rinse again.
