Daily Planetary Camera Cleaning Procedure
Daily planetary camera cleaning of lamps, film unit, document board and lens with a damp lint-free cloth to prevent image loss.

Daily cleaning of a planetary camera prevents loss of image quality and wasted cost.
Highlights
| Area | Effect of contamination |
|---|---|
| Exposure lamps | Reduced exposure and low density |
| Inside the film unit | Airborne dust on film and image loss |
| Document Board | Dust and static, and higher cost |
| Lens | Out of focus and image loss |
Clean all surfaces with a lint-free cloth slightly dampened with water. Water is naturally anti-static and prevents dust buildup for up to eight hours.
