Step 3: Wet Cleaning
While cleaning liquids of high purity offer the best
results for solid dirt and often also for remains from
oily substances they all leave residues. The following
liquids are considered suitable for cleaning:
Petroleum ether, a.k.a. benzene (high purity).
•
Isopropyl alcohol, a.k.a. isopropanol (high purity).
•
Ethyl alcohol, a.k.a. ethanol (high purity).
•
It is recommended to use moistened, lint-free swabs,
such as Texwipe® Absorbond Swabs mentioned above.
Use the swab to apply the liquid.
•
Start wiping from the inner area towards the edges first
•
and then around the edges in a circular movement.
Always leave the swabs inside the original bag
and
never use swabs twice!
Never touch the cleaning head of the swab with
fingers. If the head needs to be shaped to better
reach an area, press it against the inside of the
lid from the cleaning liquid's bottle.
If the sensor cover glass is contaminated with
particles bigger than dust (e.g. a grain of sand),
carefully pick the particle off the sensor and
continue with a new swab to avoid scratching
the cover glass surface.
NEVER USE METHANOL OR ACETONE TO
CLEAN THE SENSOR COVER GLASS!
These chemicals can dissolve paint which would
then be spread across the sensor cover glass.
This would irrecoverably damage the sensor
cover glass.
Note: To avoid smudging the inner area, always
swab around the edges as a final step.
Note: Some liquids like petroleum ether or
isopropyl alcohol are not allowed on
planes due to flight safety regulations.
Condensation
When moving the camera from a cool to a warm location
or when the camera is used in a damp environment,
condensation may form inside the lens compartment,
on the sensor cover glass, between sensor and its cover
glass, and on internal or external electrical connections.
Operating the camera in this condition may
result in personal injury or damage to the
equipment.
Condensation on the optical components may
have a visible effect on the output images.
To reduce the risk of condensation:
Find a warmer storage location.
•
Attach the included
•
air-drying cartridge (silica bottle) to
the PL-Mount of the camera when the camera is stored.
