The lens is not waterproof, if wet it should be dried with a cloth, if exposed to salt, moisten a cloth, wring it and clean.
11.6Back Maintenance
Cleaning the CCD
When the Phase One P+ back is not attached to a camera, the camera back must be protected with the protection plate. However, over time dust may accumulate on the IR filter. This will degrade the image quality if not removed.
Please follow the directions included in the CCD cleaning kit in the P+ back suitcase.
